Input Specifications
DIB 01 C M24 100A
DIB01 is a precise TRMS AC
over or under current
(selectable by DIP-switch)
monitoring relay.
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
current transformer it is pos-
sible to monitor loads up to
100 A AC.

Function/Range/Level and Time Delay Setting
Mode of Operation
DIB01 monitors AC over or
under current through an
internal current transformer.
Example 1
(connection between termi-
nals A1, Y1 - latching func-
tion enabled - Relay ND)
The relay operates and
latches 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 A1, Y1 is
interrupted or the power
supply is interrupted as well.
The red LED flashes until the
delay time has expired.
Example 2
(no connection between ter-
minals A1, Y1 - latch func-
tion disabled - Relay ND)
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 setting) or when
power supply is interrupted.
Note
When the inhibit contact is
opened, if the input signal is
already in alarmposition, the
delay time needs to elapse
before relay activation.
