Switchboard Meter Relays

General Details





Switchboard Meter Relays in the Crompton Series 007-30 are an analog meter relay style that combines a highly accurate indicator with High/Low set point relays. The relays can operate alarm and control devices when the monitored signal value moves outside the chosen set point limits shown by adjustable red index pointers. These units are IP50 rated.

Switchboard Meter Relays house a single compact case which requires only the input signal and power supply thus saving space and installation time. Applications are frequency monitoring, high & low alarms, liquid level control, load shedding, power factor correction, shutdown, and temperature indication and control. Features are Class 1.5 accuracy, isolated input signal, LED relay status indicators, in a rugged, shock and vibration resistant design. The unit offers a stable electronic switching circuit that does not used outdated lamps, photocells, inductors or capacitors.
