Monitoring Relays 1-Phase AC/DCOver Voltage - AC Over Current Types DUA01, PUA01 DUA01 PUA01 • AC/DC over voltage monitoring relay • Selection of measuring range by DIP-switches • Measuring ranges: 2 to 20 VAC/DC, 5 to 50 VAC/DC, 20 to 200 VAC/DC, 50 to 500 VAC/DC, 0.4 to 4 Vp AC • Adjustable voltage limit on relative scale • Adjustable hysteresis • Programmable latching at set level • Output: 8 A SPDT relay normally de-energized • For mounting on DIN-rail in accordance with DIN/EN 50 022 (DUA01) or plug-in module (PUA01) • 22.5 mm Euronorm housing (DUA01) or 36 mm plug-in module (PUA01) • LED indication for relay and power supply ON • Galvanically separated power supply Product Description Ordering Key DUA 01 C B23 500V DUA01 and PUA01 are pre- cise AC/DC over voltage monitoringrelays. They can also be used as 1-phase or 3-phase over currentmoni- toring relays when connect- edwithMIorMPcurrent transformers. Owing to the built-in latch function, the ON-position of the relay output can be maintained. The redLED indicatesthe alarm status.
