Dold UH5892.11PS UH AC/DC85-230V 440K Safety relay, Part N: 0067393

The insulation monitor UH 5892 of the series varimeter IMD monitors the ground resistance of  isolated DC-voltage systems (IT-systems) with nominal voltage up to DC 600 V. The unit detects symmetrical as well as unsymmetrical faults. The separate auxiliary supply of AC/DC 24...60 V or AC/DC 85...230 V allows also monitoring when the system is without voltage. To indicate the actual ground resistance value the unit has an LED chain and an analogue output. When a fault is detected the relay switches and the red LED Alarm lights up, The device can be used for system with leakage capacities up to 20 uF.
