Monitoring Relays 1-Phase True RMS AC/DCOver and Under Voltage Types DUC01, PUC01 DUC01 PUC01 • TRMS AC/DC over+under, over+over or under+under voltage monitoring relays • Selection of measuring range by DIP-switches • Measuring ranges from 2 to 500 V AC/DC • Adjustable voltage on relative scale • Adjustable hysteresis on relative scale • Adjustable delay function (0.1 to 30 s) • Programmable latching or inhibit at set level • Output: 1 or 2 x 8 A SPDT relay N.D. or N.E. selectable • For mounting on DIN-rail in accordance with DIN/EN 50 022 (DUC01) or plug-in module (PUC01) • 45 mm Euronorm housing (DUC01) or 36 mm plug-in module (PUC01) • LED indication for relay, alarm and power supply ON • Galvanically separated power supply Product DescriptionOrdering Key DUC 01 D B23 500V DUC01 and PUC01 are pre- cise TRMS AC/DC over+under, over+over or under+under voltage (selectable by DIP-switch) monitoringrelays. The volt- age levels are adjustable separately and have their own time delay. Type Selection Owingtothebuilt-inlatch function, the ON-position of the relay output can be maintained.Inhibitfunction can be used to avoid relay operation when notdesired (maintenance, transitions). The LED's indicate the state of the alarm and the output relay.
