Input Specifications

DIB 02 C B23 150mV

DIB02 and PIB02 are precise
TRMS AC/DC over or under
current (selectable by DIP­switch) monitoring relays.
The current is measured through
an external shunt. 1-phase
and 3-phase current up to
500 AAC can be monitored
connecting MI or MP current
transformers.

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.

Mode of Operation

DIB02 and PIB02 monitor
both AC and DC over or
under current through an
external shunt.

When connected with MI or
MP current transformer (using
the 0.4 to 4 V

p

range) they
can monitor 1-phase or 3­phase AC current up to 500 A.

Example 1

(connection between termi­nals Z1, Y1 or 8, 9 - latching
function enabled)

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 setting), 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 (MI CT)

(no connection between ter­minals Z1, Y1 or 8, 9 - latch
function disabled)

The relay operates when the
current flowing in the CT
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.

Example 3 (MP CT)

(no connection between ter­minals Z1, Y1 or 8, 9 - latch

function disabled - over cur­rent measurement)
The relay operates when the
maximum current flowing in
the CT exceeds the set level
for more than the set delay
time.
It releases when the maxi­mum current drops below
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 alarm position, the
delay time needs to elapse
before relay activation.
