Product description

The trip circuit monitor UG 5124 is used to monitor control and trip circuits in electrical controls. It detects interruptions of the trip circuit coil, interruptions of wires, increase resistance, welded contacts, missing control and auxiliary voltage. The setting of the both time delays is simply done on 2 rotary switches on the front of the device. As the power supply and the measuring circuit are galvanically separated, 2 different voltage sources can be connected.
