CMG-0101 Series AC Self-Powered Current Monitoring Relay

The CMG-0101 Series AC Self-Powered Current Monitoring Relay from the ATC Diversified Electronics division of Marsh Bellofram is a solid state self-powered monitoring relay that is used to detect the presence of AC current go/no-go. When the monitored current exceeds the trip point for longer than 400 msec, the output energizes (pick-up). When the monitored current drops below the trip point for longer than 400 msec, the output de-energizes (drop-out). No physical connection is required as the line to be monitored is magnetically coupled by passing the conductor through the protruding monitor current transformer. As a self-generating device, no external supply is required to operate the monitor.
