Product Description
DUB01 and PUB01 are pre-
cise TRMS AC/DC over or
under voltage (selectable by
DIP-switch) monitoring relays.
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.
