Insulation monitor
SL 5880

The insulation monitor IL 5880 of the series VARIMETER IMD monitors the insulation resistance of isolated single phase or 3-phase voltage systems (IT-systems) with nominal voltage up to AC 0 ... 500 V. The separate supply voltage (auxiliary voltage) allows also monitoring when the system is without voltage. The device has LEDs to indicate the operating status. The response value can be set in a user-friendly way on the front of the device via a potentiometer.
