Product Description Ordering Key
DIC01 and PIC01 are precise
TRMS AC/DC over+under,
over+over or under+under
current and voltage (selectable by DIP-switch) monitoring relays. DIC01 can perform also DC plus/minus
measurement by short circuiting pins Z3 and Y1. The
devices can be connected to
the MI or MP and A82 or E82
current transformers.
Both relays have two individual set levels with their own
time delay. Only for DIC01
each set level can work with
a single SPDT 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
relays.
