This digital relay has a measurable voltage of 10 to 600V 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.
