Siemens 3UG4631-1AW30 Single Phase Voltage Monitoring Relay Digital SPDT-CO

This digital relay has a measurable voltage of 0.1 to 60V AC and functions as a voltage monitoring relay for single-phase AC and DC voltages against a set threshold for overshoot and undershoot.

Typical applications for this device includes: protection of plant against destruction due to overvoltage, switch-on of plant at a defined voltage and higher, protection against overloaded supply voltages, particularly with battery power, threshold switch for analogue signals from 0.1 to 10 V.

* LCD display * Control voltage 24 to 240V AC/DC * 1CO Contact * Adjustable overshoot, undershoot or range monitoring * Freely configurable delay times and RESET response * Width 22.5 mm * Display of ACTUAL value and status messages * Screw terminals
