Monitoring Relays 1-Phase True RMS AC Over/Under Voltage Types DUB02, PUB02 DUB02 PUB02 • TRMS AC over/under voltage monitoring relays • Measuring if power supply is within set limits • Measure their own power supply • Measuring ranges: 24, 115, 230 VAC • Power ON delay 1 or 6 s selectable by DIP-switch • Separately adjustable upper/lower level on relative scale • Adjustable delay on alarm or on recovery (0.1 to 30 s) • Programmable latching or inhibit at set level • Output: 8 A SPDT relay N.D. or N.E. selectable • For mounting on DIN-rail in accordance with DIN/EN 50 022 (DUB02) or plug-in module (PUB02) • 22.5 mm Euronorm housing (DUB02) or 36 mm plug-in module (PUB02) • LED indication for relay, alarm and power supply ON 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.
