The Class 389 relays are high quality general purpose relays, designed to switch
larger loads without increasing overall size. One, two and three pole relays are
available with a choice of Indicator lamp, Push to test button and various contact
combinations. Double make and double break styles are available only with a one
pole style but is capable of switching larger loads and are especially well suited for
switching motor loads. These relays are available in the 30 Amp contact range.

SPECIFICATIONS CLASS 389 RELAYS
The 300 series was developed as a 600 Volt relay that would accept 1/4" booted
terminals. Its extra spacing permits contact gaps to 2 millimeters when required.
This increases dielectric strength across open contacts to 2500 Volts RMS.
Consult factory for details or additional information.

SEE SECTION 10 FOR MATING SOCKETS
The RSX1800 Series Alarm Relay consists of a pair of 2 pole or 3 pole
relays enclosed in a clear plastic cover. Wired to a 12 Pin Industrial plug.
The relay is wired so that it performs the basic functions of Interfacing between
a alarm point and an alarm light and/or an acoustic sounding device.
The RSX1800 operates from a normally closed trouble contact, while the
RSX1800Z operates from a normally open trouble contact. Either a sustained
or momentary alarm condition will energize the relay when signalled by an
external trouble contact. The Alarm can be allowed to continue until the
trouble has been corrected, at which time it automatically resets.

Note: The Class W92 Meets Fit and Function when replacing the Omron G7L relay. The case size ( width & lenght ) and mounting
centers on flange are Dimensionally identical except the class 92 is lower in height. The W92 has a higher contact switching
rating then the G7L and requires less coil power for operation. The 1/4" (.250) Q.C. terminals on top of the case of the Class
92 are not located in the same positions as the G7L, but wire hookup will work with existing wiring using Q.C. connectors..

MERCURY-WETTED CONTACT RELAYS. ( CONTINUED)
Mercury wetted contacts are fast in operation and have relatively good load
carrying capacity and long life. The mercury films are reestablished at each
contact closure and contact erosion is eliminated.. The mercury films are
stretchable, there is no contact bounce and because it is a mercury contact, the
contact resistance is very low and ideal for low level switching applications.
The disadvantages of this type of reed relay are the freezing point of mercury
(-38C), poor resistance to shock and vibration and the need to mount the relay in
a near vertical position.
These relays are used for a variety of switching applications such as found in
computers, business machines, machine tool control systems, and laboratory
instruments.
CONTACT COMBINATIONS.
The switches used in dry reed relays provide SPST-NO, SPST-NC, SPDT contact
combinations.
The SPST-NO corresponds with the basic switch capsule design (Fig.1).
The SPST-NC results from a combination of the SPST-NO switch and
a permanent magnet strong enough to pull the contacts closed but able to open
when coil voltage is applied to the relay coil.
In typical true SPDT designs, the armature is mechanically tensioned
against the normally closed contact, and is moved to the normally open contact
upon application of a magnetic field. The SPDT contact combination can also be
achieved by joining a SPST-NO switch with an appropriately adjusted SPST-NC
switch, and jumping one side of both switches together to form the movable contact
system.
Latching contacts, defined as contacts which remain in the position to
which they were driven, and staying in that position when coil power is removed
from the relay coil.
Latching switches are manufactured by using a SPST-NO contact, and biasing it
with a permanent magnetic that is strong enough to hold the contacts closed,
but not strong enough to hold the contact closed when coil power is applied to the
coil. The switching process is than reversed by simply reversing the relay coil
polarity to close the switch.
MAGNETIC FIELDS
Reed relays in general can be characterized as susceptible to the influences of
external magnetic fields. It is important to keep reed relays at a proper distance
from each other because of the possibility of magnetic-interaction between them.
Proper magnetic shielding must be used to contain stray magnetic fields. When
installing reed relays into equipment, one should be aware of the devices within
that equipment which can produce magnetic fields. The relays being installed into
that equipment should be positioned as far away as possible from any stray
magnetic fields and should be shielded to prevent false operations.
ELECTRICAL CHARACTERISTICS
SENSITIVITY: The input power required to operate dry reed relays is determined
by the sensitivity of the particular reed switch used, by the number of switches
operated by the coil, by the permanent magnet biasing (if used), and the efficiency
of the coil and the effectiveness of its coupling to the blades. Minimum input
required to effect closure ranges from the very low milliwatt level for a single
sensitive capsule to several watts for multipole relays.
OPERATE TIME: The coil time constant, overdrive on the coil, and the character-
istics of the reed switch determine operate time. With the maximum overdrive
voltage applied to the coil, reed relays will operate in approximately the 200
microsecond range. When driven at rated coil voltage, usually the relays will
operate at about one millisecond.
RELEASE TIME: With the coil unsuppressed, dry reed switch contacts release
in a fraction of a millisecond. SPST-NO contacts will open in as little as 50
microseconds. Magnetically biased SPST-NC and SPDT switches reclose from
100 microseconds to 1 millisecond respectively.

HOW REED RELAYS WORK
The term reed relay covers dry reed relays and mercury-wetted
contact relays, all of which use hermetically sealed reed switches.
In both types, the reeds (thin, flat blades) serve multiple functions -
as conductor, contacts, springs, and magnetic armatures.
DRY REED RELAYS
Dry reed relays have become an important factor in the relay field.
They have the advantage of being hermetically sealed and resistant
to atmospheric contamination. They have fast operate and release
times and when operated within their rated contact loads, have very
long life. A typical dry reed switch capsule is shown in Figure 1.

Figure 1. Construction of Switch Capsule of Typical Dry Reed switch (SPST-NO)
In the basic SPST-NO design, two opposing blades are sealed into a
narrow glass capsule and overlapped at their free ends. The contact
area is plated typically with rhodium to produce a low contact resistance
when contacts are drawn together. The capsule is made of glass and
filled with a dry inert gas and then sealed. The capsule is surrounded by
an electromagnetic coil. When the coil is energized, the normally open
contacts are brought together; when the coil voltage is removed, the
blades separate by their own spring tension. Some reeds contain
permanent magnets for magnetic biasing to achieve normally closed
contacts (SPST-NC) or SPDT contact combinations. The current rating,
which is dependent upon the size of the blade and the type and amount
of plating, may range from low level to 1 amp. Effective contact protection
is essential when switching loads other then dry resistive loads.
MERCURY-WETTED CONTACT RELAYS.
Mercury wetted contacts consist of a glass-encapsulated reed with its
base immersed in a pool of mercury and the other end capable of moving
between one or two stationary contacts. The mercury flows up the reed by
capillary action and wets the contact surfaces of the moving end of the
reed as well as the contact surfaces of the stationary contacts. A mercury
to mercury contact is maintained in the closed position. The capsule is
surrounded by an electromagnetic coil and operates in the same manner
as a dry reed.
APPLICATION DATA
REED
RELAYS
ELECTRICAL CHARACTERISTICS (Continued)
RELEASE TIME (Continued)
If the relay coil is suppressed, release times are increased. Diode suppres-
sion can delay release times for several milliseconds, depending on coil
characteristics, coil voltage, and reed release characteristics.
CONTACT BOUNCE
Dry reed contacts bounce on closure as with any other hard contact relay.
The duration of bounce on a Dry reed switch is typically very short, and is
in part dependent on drive level. In some of the faster devices, the sum of
the operate time and bounce is relatively constant. As drive is increased, the
operate time decreases with bounce time increasing.
The normally closed contacts of a SPDT switch bounce more then the
normally open contacts. Magnetically biased SPST-NC contacts exhibit
essentially the same bounce characteristics as SPST-NO switches.
CONTACT RESISTANCE
The reeds (blades) in a dry reed switch are made of magnetic material
which has a high volume resistivity, terminal-to-terminal resistance is
somewhat higher than in some other types of relays. Typical specification
limits for initial resistance of a SPST-NO reed relay is 0.200 ohms max
(200 milliohms).
INSULATION RESISTANCE
A dry reed switch made in a properly controlled internal atmosphere will
have an insulation resistance of 10
12
to 10
13
ohms or greater. When it is
assembled into a relay, parallel insulation paths reduce this to typical values
of 10
9
ohms. Depending on the particular manner of relay construction,
exposure to high humidity or contaminating environments can appreciably
lower final insulation resistance.
CAPACITANCE.
Reed capsules typically have low terminal-to-terminal capacitance.
However, in the typicall relay structure where the switch is surrounded by a
coil, capacitance from each reed to the coil act to increase capacitance
many times. If the increased capacitance is objectionable, it can be
reduced by placing a grounded electrostatic shield between the switch and
coil.
DIELECTRIC WITHSTAND VOLTAGE
With the exception of the High-Voltage dry reed switches ( capsules that
are pressurized or evacuated), the dielectric strength limitation of relays is
determined by the ampere turn sensitivity of the switches used. A typical
limit is 200 VAC. The dielectric withstand voltage between switch and coil
terminals is usually 500 VAC.
THERMAL EMF
Since thermally generated voltages result from thermal gradients within the
relay assembly, relays built to minimize this effect often use sensitive
switches to reduce required coil power, and thermally conductive materials
to reduce temperature gradients. Latching relays, which may be operated
by a short duration pulse, are often used if the operational rate is not
changed for longer periods of time because coil power is not required to
keep the relay in the on or off position after the initial turn on or turn off
pulse.
NOISE
Noise is defined as a voltage appearing between terminals of a switch for a
few milliseconds following closure of the contacts. It occurs because the
reeds (blades) are moving in a magnetic field and because voltages are
produced within them by magnetostrictive effects. From an application
standpoint, noise is important if the signal switched by the reed is to be used
within a few milliseconds immediately following closure of the contacts.
When noise is critical in an application, a peak-to-peak limit must be
established by measurement techniques, including filters which must be
specified for that particular switching application.
ENVIRONMENTAL CHARACTERISTICS
Reed relays are used in essentially the same environments as other types of
relays. Factors influencing their ability to function would be
temperature extremes beyond specified limits
VIBRATION
The reed switch structure, with so few elements free to move, has a better
defined response to vibration than other relay types. With vibration inputs
reasonably separated from the resonant frequency, the reed relay will
withstand relatively high inputs, 20 g's or more. At resonance of the reeds,
the typical device can fail at very low input levels. Typical resonance
frequency is 2000 hz.
SHOCK
Dry reed relays will withstand relatively high levels of shock. SPST-NO
contacts are usually rated to pass 30 to 50 g's, 11 milliseconds, half sign
wave shock, without false operation of contacts. Switches exposed to a
magnetic field that keep the contacts in a closed position, such as in the
biased latching form, demonstrate somewhat lower resistance to shock.
Normally closed contacts of mechanically biased SPDT switches may also
fail at lower shock levels.
TEMPERATURE
Differential expansion or contraction of reed switches and materials used in
relay assemblies can lead to fracture of the switches. Reed relays are
capable of withstanding temperature cycling or temperature shock over a
range of at least -50C to + 100C. These limits should be applied to the
application to prevent switch failure.
CONTACT PROTECTION
Tungsten lamp, inductive and capacitive discharge load are extremely
detrimental to reed switches and reduce life considerably. Illustrated below
are typical suppression circuits which are necessary for maximum contact
life.
DC inductive loads call for either a diode or a thyristor to be placed across
the load. These circuits are necessary to protect the contacts
when inductive loads are to be switched in a circuit, as shown in Figure 4.
FIGURE 4
Input
Input
Initial turn-on current is generally 10 times higher than the rated
operating current of the lamp. A current limiting resistor in series with
the load, or a bleeder resistor across the contacts will suppress the
inrush current. Thesesame circuits can be used with capacitive loads,
as shown in Figure 3.

INTRODUCTION:
SOLID STATE RELAY (SSR) is a relay with isolated input and output,
whose functions are achieved by means of electronic components without
the use of moving parts as found in Electromechanical relays.
PRINCIPLE OF OPERATION:
Solid State Relays are similar to Electromechanical relays, in that both use
a control circuit and a separate circuit for switching the load. When voltage
is applied to the input of the SSR, the relay is energized by a light emitting
diode. The light from the diode is beamed into a light sensitive semiconduc-
tor which, in the case of zero voltage crossover relays, conditions the
control circuit to turn on the output solid state switch at the next zero voltage
crossover. In the case of nonzero voltage crossover relays, the output solid
state switch is turned on at the precise voltage occurring at the time.
Removal of the input power disables the control circuit and the solid state
switch is turned off when the load current passes through the zero point of
its cycle.
APPLICATIONS:
Solid State Relays are specially suitable in many applications.
Listed below are some typical applications.
Microprocessor-based Controls.
Computers and Computer Peripherals.
Process control Systems using PLCs
Temperature Control Systems.
Business Machines
Medical Equipment
Uninterrupted Power Supplies (UPS).
Communication
Traffic Signals, etc.

LOAD CONSIDERATIONS
A major portion of application problems with SSR's result from operating
conditions which specific loads impose upon an SSR. The following types
of loads point out the potential problems that can occur with SSR's.
LOAD CONSIDERATIONS (cont.)
DC LOADS: All loads should be considered inductive and a Diode
should be placed across the load to absorb any inductive surge on
turnoff.
RESISTIVE LOADS: Loads of constant value resistance are
probably the simplest application of SSR's. Proper attention to the
steady state current ratings and applied blocking voltage specifica-
tions normally will result in trouble-free operation.
LAMP LOADS: Incandescent lamp loads, though basically
resistive, present some special problems. Because the resistance
of a cold tungsten filament is about five to ten percent of the
heated value, a large inrush current can occur. The period of the
inrush current can range from one half cycle to several cycles.,
depending on the thermal time constant of the filament. It is
essential to verify that this inrush current is within the surge
specifications of the SSR. Also check that the lamp rating of the
SSR is not exceeded. This is a UL rating based on the inrush of a
typical lamp. Because of the unusually low filament resistance at
the time of turn-on, a zero voltage turn-on characteristic is
particularly desirable with tungsten lamps.. It has been demon-
strated that a zero voltage turn-on can extend the life of tungsten
lamps by limiting inrush current.
CAPACITIVE LOADS: Caution must be used with low impedance
capacitive loads to verify that the di/dt capabilities are not
exceeded. The di/dt of a discharged capacitive load with out
external limiting impedance can approach infinity. Zero voltage
turn-on is a particularly valuable means of limiting di/dt with
capacitive loads.
MOTORS: Specifically, motors frequently have severe inrush
currents during starting and can impose unusual voltages during
turnoff. The inrush currents connected to mechanical loads having
high starting torque or inertia should be carefully determined to
verify that they are within the surge capabilities of the SSR. A
current shunt and Oscilloscope should be used to examine the
duration of the inrush current. Motor starting may frequently
reoccur at short intervals and the affect of repetitive inrush currents
on the thermal operating point of an SSR must be considered.
Check the motor operating current and locked rotor current versus
the SSR motor rating. The possibility of abnormally stalled rotor
conditions which draw much higher than normal currents should be
considered. An extended stalled rotor condition may require an
oversized SSR or fuse protection. The generated EMF of certain
motors can require an SSR to have a blocking voltage greater than
might be expected from steady state line voltage. The voltage
applied to an SSR by a motor circuit during turnoff should be
examined with an oscilloscope to verify hat the applied voltages
are safely below the specified SSR blocking voltages. Otherwise
lock-on or erratic turnoff of the motor may occur. Some motor
circuits may require higher than normal blocking voltage, transient
limiting devices, or other techniques to control the voltage which
must be blocked by an SSR during deceleration or direction
reversal.

TRANSFORMERS
In controlling transformers, the characteristics of the secondary load should
be considered because it reflects the effective load on the SSR. Voltage
transients from secondary load circuits, similarly, are frequently transformed
and can be imposed on the SSR. Transformers present a special problem
in that, depending on the state of the transformer flux at the time of turnoff,
the transformer may saturate during the first half-cycle of subsequent
applied voltage. This saturation can impose a very large current (Com-
monly ten to one hundred times rated primary current) on the SSR and
exceed its half-cycle surge rating.
SSR's having random turn-on may have a better chance of survival than a
zero voltage turn-on device for they commonly require the transformer to
support only a portion of the first half-cycle of the voltage. On the other
hand, a random turn-on device will frequently close at the essentially zero
voltage point (start of the half-cycle) and then the SSR must sustain the
worst-case saturation current. A zero voltage turn-on device has the
advantage that it turns on in a known, predictable mode and will normally
immediately demonstrate (dependent on turnoff flux polarity) the worst-case
condition. The use of an oscilloscope is recommended to verify that the
half-cycle surge capability of the SSR is not exceeded. The severity of the
transformer saturation problem varies greatly, dependent on the magnetic
material of the transformer, saturated primary impedance, line impedance,
etc.
A safe rule of thumb in applying an SSR to a transformer primary is to select
an SSR having a half-cycle current surge rating (RMS) greater than the
maximum applied line voltage (RMS) divided by the transformer primary
resistance. The primary resistance is usually easily measured and can be
relied on as a minimum impedance limiting the first half-cycle of inrush
current. The presence of some residual flux plus the saturated reactance of
the primary will then further limit, in the worst case, the half-cycle surge
safely within the surge rating of the SSR.
SELECTING THE PROPER SSR
NOMINAL LOAD CURRENT: Initially select a relay whose current rating
exceeds the normal load current. Using the load current vs. temperature
chart for that relay, check the actual current capacity at the ambient
temperature to which the relay will be subjected.
As an example, the chart below shows that a 25 ampere relay provided with
a suitable heat sink can safely carry a maximum of 17 amperes continu-
ously at 40C ambient. Since heat degrades the output semiconductor
every effort should be made to keep the operating temperature of the SSR
as low as possible

PROTECTING THE OUTPUT SWITCH
An SSR is a four layer semiconductor having 3 terminals:
Cathode, Anode and Gate. Normally it blocks current in both the
forward and reverse directions. The SCR is triggered on in the
forward direction by a small gate current. The SCR remains on
until load current decreases to a value less than necessary to
maintain the SCR in the on state. When switching AC, two SSR's
are connected in inverse parallel.
A Triac also has 3 terminals, like the SCR, it normally blocks
current in both directions; but may be triggered in either direction
by a small gate current
Both SCR's and Triacs are members of the thyristor family.
Therefore, we use this term to denote both devices. There are 4
ways to put a thyristor into a conducting mode. Only one method
is desirable and the other three are the source of most application
problems.
The 4 methods of Thyristor turn-on are -
A. Gate Turn-on: By injecting a controlled current into the gate
(the desired method).
B. Forward Breakover Turn-on: A voltage in excess of the
Breakover (or Peak Blocking) voltage across Thyristor.
C. DV/DT turn-on: A voltage which rises faster than the Thyristor
can tolerate, and still remain in the off state.
D. Thermal Turn-on: Allowing the temperature of the thyristor to
go beyond the value sufficient to cause excessive leakage
current, causing turn-on and possible thermal runaway.
The last three methods can be protected against as follows. In
those situations where high peak voltage transients occur, effective
protection can be obtained by using metal oxide varistors (MOV).
The MOV is a bidirectional voltage sensitive device that has low
impedance when its design voltage threshold is exceeded.
HEAT SINKING
It is important to select the right size heat sink for your applications.
SSR's will typically generate 1.2 watts per amp of load current.
The maximum junction temperature of the output device is 115C.
The total wattage is divided by the thermal resistance to get the
temperature difference between the output device junction and the
ambient temperature. For example a 25 Amp SSR with a 20 Amp
load applied dissipates 24 watts when mounted on a aluminum
plate 6" X 6" X 1/8" with thermal grease applied between the SSR
base and aluminum plate. This combination produces a output
junction temperature rise of 24 watts. 24W times (1 c/w relay +
1 c/w (heat sink) = a operating temperature of 48C.
FUSING
THE SSR has a I
2
T rating which is a measure of the amount of
energy it can safely handle without damage. The I
2
T rating of the
fuse is a measure of the amount of energy the fuse will pass to the
SSR. To protect the SSR, the I
2
T of the Fuse should be less than
that of the SSR. An SSR exposed to a surge greater than its non-
repetitive rating will normally fail as a shorted unit.

WHAT A TIME DELAY RELAY IS:
A Time Delay relay is a combination of an electromechanical output
relay and a control circuit. The control circuit is comprised of solid state
components and timing circuits that control operation of the relay and
timing range. Typical time delay functions include On-Delay, Off-Delay,
Repeat cycle, One Shot, Batch Control Interval, On-Delay & Off Delay
(Combination) and True Off Delay. Each function is explained below.
Time delay relays have a broad choice of timing ranges from less than
one second to hours. There is a choice of timing controls from calibrated
external knob, screwdriver adjusted or internally fixed timing for specific
applications. The output contacts on the electromechanical output relay
are direct wired to the output terminals. The contact load ratings are
specified for each specific type of time delay relay.
TIMING FUNCTIONS:
Some typical Applications: Signs, Product testing, signal devices,
machine control, Signal warning devices, conveyor control.

INPUT
POWER
REPEAT CYCLE (FLASHER) -
Upon application of power to the input,
the Off time delay Period begins. The contacts transfer at the end of the
Off time Delay Period and the ON time delay period begins. At the end
of the ON time delay period output contacts return home and OFF time
delay period begins again. This sequence will continue as long as input
power is supplied to the Input Pins.
Some typical Applications: Air Conditioning, automatic Door Controls,
Lighting Controls, burglar alarms, Vending Machines, conveyor
systems, instrument control.

Some typical Applications: Cascade starting, Air Conditioning & heating
controls, Burglar Alarms, Power Outage delay, instrument Control.
OFF-DELAY (SLOW RELEASE RELAY)
Continuous power must be applied to input during all timing sequences.
Upon closure of external control switch, output contacts transfer. Upon
opening control switch, the timing period begins. When timing period
ends, output contacts return home. To repeat this timing cycle, the
control switch must be re-closed and then opened. If input power is
interrupted during timing cycle, the output contacts return to home
position and the control switch must be closed and reopened to start the
timing from the beginning. If the control switch closes during a timing
period, timing stops and output contacts remain transferred. When control
switch is opened, timing will start again from the beginning. The timing
period can be extended, repeatedly using the control switch in this way
until the last initiated timing period is permitted to end and output contacts
return home.

Some typical Applications: Loss of power alarm control, Burglar
alarms.

TRUE OFF DELAY- (SLOW RELEASE)
Upon application of power to the input, output contacts transfer. The
delay period begins when power is removed from the input. If power
is supplied to input during the timing period, time is reset and time
delay period starts over again when power is removed from the input.
Some typical Applications: Cascade starting & stopping of heavy
loads, laboratory equipment, machine control

ON-DELAY & OFF-DELAY- (COMBINATION)
Continuous power must be applied to the input during all timing
sequences. Upon closure of the external control switch, first time delay
period T
1
begins. When T
1
period ends, output contacts transfer.
Then, When control switch is opened, second delay period T
2
begins.
When T
2
ends, output contacts return home. To repeat this timing
cycle, repeat this sequence from the beginning. If the prevailing open
or closed status of the control switch is changed during either T
1
or T
2
Timing periods, timing stops. Position of output contacts remain as they
were. Returning control switch to its pre-changed position restarts
interrupted timing period from the beginning and normal timing resumes.
Some typical Applications: Machine control, End of process alarm,
Welding control, Photographic timing.

Upon application of power to the input, the output contacts transfer
and the delay period begins. At the end of the time delay period, the
output contacts return home. Input power must be interrupted to

FUNCTIONS
APPLICATION DATA
ON-DELAY- (SLOW OPERATE RELAY)
Upon application of power to
the input, the time delay period begins. At the end of the time delay
period, output contacts transfer. Input power must be removed to return
output contacts to home position and reset the control circuit. If input
power is interrupted before a timing period ends, timing stops. When
input power is restored , timing starts from the beginning.
Special requirements for Class 211 programmable relays: To function as
an On-Delay timer, as described above, a jumper wire must be connected
in place of the external control switch.

ONE SHOT (MOMENTARY ACTUATION)
Continuous power must be applied to the input during all timing
sequences. Upon closure of external control Switch, output contacts
transfer and timing period begins. When timing period ends, output
contacts return home. Once the timing period begins, the control
switch may remain closed or opened without affecting timing. To
repeat this cycle, the control switch must be open, or opened at the
end of the timing period, and then closed to start timing period over
again.

SELECTING A TIMER'S MODE OF OPERATION
Selecting the correct Mode of operation (Timing Function) can be easily done by following the ladder diagram below. When selecting the
proper relay for your application, you must determine if the timer will be controlled by input power only, or the use of an external switch.
The next item to take into consideration is the load status during the timing cycle(s), and the contact status after the timing cycle.
NOTES:
1. Momentary power supplied to the input. Input power not required for timing cycle.
2. Continues to repeat timing cycles until power is removed from input
3. Upon closure of External switch, relay contacts switch and time period begins. The timing is not affected by the duration
of the External switch closure.
4. External switch is maintained closed, relay contacts switch at the end of first timing cycle.
5. External switch is maintained open for second timing cycle.
Footnote: ON = Relay coil energized, contacts switched. OFF = Relay coil de-energized, contacts in normal position.

The Class 388 Adjustable True Off Delay
Relay combines a Solid State Timing circuit
with a state of the art Magnetic Latching
relay. This combination allows the relay
to Pull-in when power is applied to the input.
Timing starts when power is removed from
the input and at the end of the preset timing
period the relay will dropout.

Typical Part Number
Code 012**- 12 Second timing not available on 237 & 238 models.
(F * Models) - timing code does not apply. Specify single delay time requirement.
Example of typical fixed time delay relay part number- 236XBXP-3.5F-120A
(ON DELAY, DPDT, 3.5 SEC FIXED, 120 VAC INPUT POWER).
NOTES:
1. 236,237,238 - External resistor (to program time delay) or jumper (for
built-in timing) must be connected to terminals 8 & 9.
2. 237 models require an external control switch between terminals 5 & 6.
3. 238 switches contacts when input power is applied and starts timing.
Contacts switch back to original position at end of timing cycle. Power must
be removed to reset timer. If input power is interupted during the timing
cycle, timing ends immediately and the relay resets.
4. Dielectric withstanding voltage testing of the Control circuit may damage
the solid state components.
SEE SECTION 10 FOR MATING SOCKETS
GENERAL SPECIFICATIONS

50,100 & 200 AMP SINGLE POLE DC CONTACTORS
The Series 101, 102 and 103 are DC solenoid-actuated, heavy duty contactors.
Each contactor has a single pole, double-make normally open contact. Contacts
are enclosed with a molded plastic cover. The series 101 is rated at 50 amps
continuous duty. The series 102 is rated 100 amps continuous and the series 103 is
rated at 200 amps continuous. Coils are rated for DC only, as standard. The powerful
magnetic structure creates very high contact pressure which results in very reliable
and low resistance contacts, making them suitable for power applications in telecom-
munications, elevator and rail mass transit as well as other Industries.

The Series 214 Ground fault interrupt relay (GFI) to our knowledge, the smallest
relay ever, to pass Underwriters Laboratories 20 Amp overload test for ground fault
interrupting devices. Both resistive and Inductive loads of 120 Amps at 120 volts
must be switched ten times each without failure. The 214 GFI is most commonly
found in portable (plug) GFI equipment. This relay is also appropriate for other
applications where size, weight, and the ability to safely handle occasional severe
overloads is of primary importance.

HERMETICALLY SEALED IN STEEL TUBES
Every contactor tube is hermetically sealed to provide
maximum life, protection to the user from arcing and the
hazards of switching heavy loads with exposed contacts.
LIQUID MERCURY CONTACT
Liquid mercury means a new contact surface after
every operation. Mercury is self-renewing, it cannot
pit, weld, disintegrate or oxidize. The internal
resistance of the contact surfaces typically measure
only a few Milliohms and is ideal for switching large
loads safely.

MERCURY DISPLACEMENT TUBE
The sectional view shows our normally open style Mercury Displacement tube with the plunger assembly
floating on the mercury pool.
When the coil power is off, the mercury level is below the electrode tip. No electrical path exists between
the electrode and mercury pool.
When coil power is applied, the plunger is drawn down into the mercury by the pull of the magnetic field.
This action raises the mercury level, so it covers the end of the electrode closing the circuit.
When coil power is turned off, the buoyant force of the mercury causes the plunger assemble to rise,
dropping the mercury level, and breaking the circuit.
Mercury Displacement relays are ideal for adverse environments-
....Where high inrushes are encountered
....Where hermetically sealed contact operation is required because of corrosive, dirty, or moist ambient
conditions.
....Where use does not permit contact maintenance.
....Where reduced noise levels are required.
....where minimum weight and size are desired.
Liquid Mercury Contact - provides a new contact surface with every actuation. Mercury is self-renewing
and does not pit, weld, disintegrate or oxidize.
Hermetic sealing - provides internal and external protection from arcing.
Inert Gas atmosphere - contactor tube is evacuated, then pressurized with a combination of gases which
extinguish arcing and contribute to long life. The pressurized gases provide for a high dielectric withstand-
ing voltage between contact surfaces.
Low Contact Resistance - Large electrode and mercury volume creates low contact resistance and
provides high inrush current capability.
Quiet Operation - Switch clacking normally associated with conventional hard contactors, is eliminated
with mercury displacement tubes and the buffer spring assembly.
The series "ML" is physically the same as the "M" series except for the type of gases used in the
contactor tubes. The "ML" series was developed for use with resistive and tungsten loads on AC power
ONLY. The "ML" series will give much greater life than the "M" series for these types of loads and is
intended for high activation use, such as molding machines or ovens.
The "ML" series, however is not intended for use with motor loads on AC power, or for resistive, tungsten,
or motor loads on DC power. The "M" series, which is our universal series is rated
to be used on all types of loads resistive, tungsten, and motor for both AC and DC power

The Series 102 and 103 are solenoid types utilizing a DC coils with a full wave bridge
rectifiers which allows the device to operate from an AC supply. Coil power consump-
tion is less than 10 watts for the series 102, less than 20 watts for the 103. The
contacts are Double make type, each set capable of switching and continuously
carrying at least 50 Amps for the series 102 and 100 Amps for the series 103 at up to
480 volts AC. The contactors are typically constructed and wired to be directly
interchangeable with existing hour meter base with separate wire leads for connection
to the controlling device. Because of their compact construction, these contactors can
be adapted to retrofit almost any existing type. Contact our Factory for details.

SEQUENCE &
LATCHING RELAY
APPLICATION NOTES
WHAT IS A SEQUENCE RELAY:
A Sequence relay is sometimes called an alternator,
stepper, flip-flop, or impulse relay. The relay has the ability
to open and close it's contacts in a preset sequence. All
sequence relays use a ratchet or catch mechanism to
cause their contacts to change state by repeated impulses
to a single coil. Usually, but not always, one pulse will
close a set of contacts, the next will open them, and so on
back and forth. This alternating of open and closed states
has many possible uses.
A Sequence relay requires a pulsed voltage to the coil
of approximately 50 milliseconds for each sequence to
take place. When the coil is pulsed, the relay armature
moves a lever that in turn rotates the ratchet and cams to
the first position in the sequence. This position will remain
as long as another pulse is not introduced to the coil.
The relay is normally comprised of at least two sets of
contacts to allow the contacts to alternate in combinations
of open and closed states, with each pulse of voltage to
the coil.
One example of possible two pole combinations, would be
where one pole remains open and the other pole is closed
with the first pulse applied to the coil. The second pulse
could then reverse the above sequence. The third pulse
could have both poles closed and the fourth pulse could
open both poles. The above example could also have
other sequences, depending upon the amount of teeth in
the ratchet and the amount of lobes on the cams.
Figure 1 shows an example of how cam placement on the
contact blades can change the position of the contacts as
cams are rotated by the ratchet gear.

FIGURE 1
SEQUENCE APPLICATIONS:
Some typical applications for sequence relays is turning
one device on and off from a single momentary contact.
SEQUENCE APPLICATIONS CONTINUED:
A typical example is remotely starting and stopping a
conveyer from a single momentary push button. Several
momentary push buttons might be wired in parallel to
control the conveyer from a number of locations.
Another common use for sequence relays is cascade
starting of multiple HVAC or other high start-up load
systems, to limit the high starting current.
WHAT IS A LATCHING RELAY:
Latch relays typically use a permanent magnet or
mechanical catch to hold the contacts in their last
energized position without the need for continued
application of coil power. They are especially useful in
applications where power must be conserved, such as a
battery operated device, or where it is desirable to have
a relay stay in one position if power is interrupted. They
should not be used to control a device that could create
a safety hazard if it were to restart after a power inter-
ruption.
Mechanical latch relays are most often constructed in a
way that will cause them to go to their operate position
when the operate coil is energized regardless of whether
the reset coil is energized or not. This "operate coil
dominant" feature can be useful in applications where a
relay should operate and release like a conventional
relay unless a particular action takes place, at which
time the release coil would drop out, latching the relay in
the operate position. A pallet loader would be a good
example of equipment which might utilize this type of
operation.
Magnetic latching relays are typically designed to be
polarity sensitive. When voltage is momentarily applied
to the coil with a predetermined polarity, the relay will
operate. The relay will remain in the operate position
after power is removed from the coil. A permanent
magnetic is designed to hold the contacts in the operate
position without the need for continued power to the coil.
When the polarity is reversed, and momentarily applied
to the coil, the armature will push away from the coil
overcoming the holding affect of the permanent mag-
netic, causing the contacts to reset. Both single and
dual wound coils use the same principle of operation.

The series 308 relay combines the basic features of the 284 series relay into a
permanent magnet latch relay. It is available with a single wound AC or DC coil.
To operate the single-wound DC coil, voltage of proper polarity is applied to the coil,
and reset when the polarity is then reversed. For AC coils, power is applied through
the operate diode or the reset diode to provide the required function.

THE SERIES B255 IS A TWO COIL LATCHING VERSION OF THE GENERAL PURPOSE
TYPE 219 RELAY. WHEN THE OPERATE COIL IS MOMENTARILY ENERGIZED, THE
RELAY MECHANICALLY LATCHES IN THE ENERGIZED POSITION AND REMAINS IN THE
ENERGIZED POSITION WITH THE POWER REMOVED FROM THECOIL. THE SECOND
COIL WHEN MOMENTARLY ENERGIZED, PROVIDES ELECTRICAL RESET OF THE
CONTACTS. ALL CONTACTS OPERATE FROM A COMMON ARMATURE TO PREVENT
CONTACT OVERLAPPING. COILS ARE RATED FOR CONTINUOUS DUTY. NUCLEAR
QUALIFIED VERSIONS ARE AVAILABLE. CONTACT THE FACTORY FOR DETAILS.

NOTE: Applying a momentary pulse to that coil which
was NOT LAST ENERGIZED, will cause a transfer of
all contacts. The mechanical latch will maintain all contacts
in the last transferred position even after the coil is de-
energized or power is interrupted. Re-transfer of contacts
can be accomplished by a momentary pulse to the other coil.

The A311 Series Relay is a sequencing version of the 219 series
general purpose relay. Contacts transfer on each Impulse to the coil.
Models are available with contacts transferring when coil is energized
or when de-energized. A double cam movement, one cam per snap
switch, allows one or both contacts to be energized or de-energized
with the cam rotating one half-step when the coil is energized and the
other half step when the coil is de-energized assures reliable sequencing
of the two SPDT snap switches.

The C85 Series Relay is a base mounted, screw terminal, open style sequencing relay.
This two pole relay has a single coil which operates a ratchet wheel. Control cams, on the
ratchet wheel shaft, step from one position to the next on each Impulse to the coil. A 50
millisecond pulse will step the relay. Coils are for momentary duty only. The C85 may be
supplied in any sequence up to 12 steps. Contacts are single throw.

OPTIONS (CONSULT FACTORY)
Struthers-Dunn
The 112 and 112-PGF Series of very low coil power relays, perform the same function
but differ in physical packaging and terminations. Each is available with SPDT or DPDT
contact arrangements. The coils require as little as 11.4 mW or 51.7 mW of DC coil power
respectively. All 112's are available with AC or DC coils. AC coils can withstand 5 times
their minimum rating, while DC coils can withstand 10 times their minimum rating, up to
300 volts. One application for this relay is to detect high resistance grounds which could
have low leakage current.

Sockets fit Class 78 style relays. The sockets are manufactured
with "floating" (loose) P.C. terminals that allow the terminals to
aline with holes in the circuit board without binding or bending
to get correct fit and alignment of terminals. The 4 pole socket
has an additional receptacle and solder terminal for grounding
4 pole relays.
