Relay Output Monitors

Relay output monitors detect abnormal output of industrial relays and trigger a logical output or set of contacts. Common detection types include; AC and DC current or voltage, voltage asymmetry, ground fault, temperature monitoring, phase loss, and sequence or imbalance. They are selectable by trip range, delay time, supply voltage, mounting type, and switch circuitry.
