ABB CM-EFS.2S VOLTAGE MONITORING RELAY CONTROL 24 - 240 V AC/DC 2CO DOUBLE CHAMBER CAGE TERMINALS

The Voltage Monitoring Relay is designed for both over- and undervoltage monitoring. It uses a RMS measuring principle to measure DC and AC voltages in four different ranges: 3-30 V, 6-60 V, 30-300 V, and 60-600 V. This relay operates with a rated control supply voltage of 24 - 240 V AC/DC. It has two CO (SPDT) outputs with contacts rated at 250 V / 4 A. The double-chamber cage connection terminals ensure secure connections. The Voltage Monitoring Relay offers window monitoring for both over- and undervoltage conditions. It also allows for the selection of ON or OFF delay, as well as open or closed circuit operating principles. Additionally, it can be used with or without a latching function. The tripping delay and start-up delay of this relay are adjustable within a range of instantaneous to 30 seconds (0, 0.1-30 s). This flexibility allows for precise customization based on specific requirements. Overall, the Voltage Monitoring Relay provides reliable and accurate monitoring of voltage levels, making it an essential component in various electrical systems.
