The CM-SRS.2 series Current Monitoring Relay can be used for overcurrent or undercurrent monitoring in 1-phase AC and DC systems. This device features monitoring of true RMS values. The current to be monitored (measured value) is applied to terminals B1/B2/B3-C. If the measured value exceeds or drops below the selected trip point value, the output relay energize on the CM-SRS.2 after the trip delay TV. The relay de-energizes when the current returns to an acceptable level. The adjustable hysteresis prevents rapid cycling. The hysteresis is adjustable 3 to 30% of the threshold value.
