Product Description
DUB02 and PUB02 are pre-
cise TRMS AC window volt-
age monitoring relays.
The relays monitor their own
power supply which is select-
able by DIP-switch (24, 115 or
230 VAC).
The advantage of using the
latch function is that the
relay can be kept energized
even after the end of the
alarm condition. Inhibit func-
tion can be used to avoid
relay operation when not
desired (maintenance, transi-
tions).
The LED's indicate the state
of the alarm and the output
relay.
