Product DescriptionOrdering Key
DUB 02 C T23
DUB02 and PUB02 are pre- cise TRMS AC windowvolt- 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 isthat 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.
