Analog Meter Relays
Analog Meter Relays in the model 239 series combine a highly accurate indicator with High and 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.
Analog Meter Relays have a single compact case that houses the unit which requires only the input signal and power supply thus saving space and installation time. These units are IP50 rated for the enclosure.
Advantages are an isolated input signal, LED relay status indicators, and a stable electronic switching circuit which does not use outdated lamps, photocells, inductors or capacitors. These units are rugged, shock and vibration resistant in design, and are used for Frequency monitoring, High & Low alarms, Liquid level control, Load shedding, Power factor correction, shutdown applications, and temperature indication and control.
