Input Specifications
DIB 01 C B23 5A
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.
