Product Description
Ordering Key
S 195 156 024
Level control relays for con-
ductive liquids which can
control two levels of charg-
ing or discharging. When the
relays are used for register-
ing only one level, the sensi-
tivity is half as large.

Mode of Operation
The switch at the front is set in
the desired mode IN (charging)
or OUT (discharging).
Connection cable
2 or 3 core PVC cable, nor-
mally unscreened. Cable
length: max. 100 m. The
resistance between the cores
and the ground must be at
least 220 k
. In certain cases
it is recommended to use
screened cable between sen-
sor and amplifier, e.g. where
the cable is placed in parallel
to the load cables (mains).
The screen is connected to
pin 7.
Example 1 and 3
The diagram shows the level
control connected as max.
and min. control, i.e. regis-
tration of 2 levels. The relay
operates (OUT)/releases (IN)
when the liquid reaches the
max. electrode (pin 5), pro-
vided that the min. electrode
(pin 6) is in contact with the
liquid.
The relay releases (OUT)/-
operates (IN) when the min.
electrode is no longer in
contact with the liquid. Pin 7
must be connected to the
container. If the container
consists of a non-conduc-
tive material, an additional
electrode must be used. (To
be connected to pin 7. In the
diagram this electrode is
shown by the dotted line.
Example 2 and 4
The diagram shows the level
control connected as max.
or min. control, i.e. registra-
tion of 1 level. The relay
operates (OUT)/releases (IN)
when the electrode (pin 6) is
in contact with the liquid. An
additional electrode must be
used if the container con-
sists of a non-conductive
material. Interconnect pins 5
and 6 directly on the base.
