Monitoring Relays
1-Phase True RMS AC/DC Over or Under Current
Types DIB02, PIB02
Product Description
DIB02 and PIB02 are precise
TRMS AC/DC over or under
current (selectable by DIP-
switch) 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.
