DIB01 and PIB01 are precise
TRMS AC/DC over or under
current (selectable by DIP-
switch) monitoring relays.
Direct measuring or through
current transformer.
Owing to the built-in latch
function, the ON-position of
the relay output can be
maintained. Inhibit function
can be used to avoid relay
operation when not desired
(maintenance, transitions).
The LED's indicate the state
of the alarm and the output
relay. Through the built-in
shunt it is possible to moni-
tor loads up to 10 A AC/DC.

for models DIB01xxx10A
and PIB01xxx10A).
Select the desired function
setting the DIP switches 3 to
6 (1 to 4 for DIB01xxx10A
and PIB01xxx10A) as shown
below.

DIB01, PIB01
Function/Range/Level and Time Delay Setting
Mode of Operation
DIB01 and PIB01 monitor
both AC and DC over or
under current through an
internal shunt.
Example 1
(connection between termi-
nals Z1, Y1 or 8, 9 - latching
function enabled)
The relay operates and latch-
es
in operating position
when the measured value
exceeds (or drops below) the
set level for more than the
set delay time. Provided that
the current has dropped
below (or has exceeded) the
set point (see hysteresis set-
ting), the relay releases when
the interconnection between
terminals Z1, Y1 or 8, 9 is
interrupted or the power
supply is interrupted as well.
The red LED flashes until the
delay time has expired or the
measured value comes back
to a non-alarm value (see
hysteresis setting).
Example 2 (Stardard CT)
(no connection between ter-
minals Z1, Y1 or 8, 9 - latch
function disabled)
The relay operates when the
measured value exceeds (or
drops below) the set level for
more than the set delay time.
It releases when the current
drops below (or exceeds) the
set level (see hysteresis set-
ting) or when power supply
is interrupted.
Note
When the inhibit contact is
opened, if the input signal is
already in alarm position, the
delay time needs to elapse
before relay activation.
