DUB02 and PUB02 are precise TRMS AC window voltage monitoring relays.

The relays monitor their own power supply which is selectable 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 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.
