ABB CM-WDS Monitoring Relay

The monitoring relay, also known as a monitoring module, control relay, or protection relay, with the type number CM-WDS from ABB is an electrical relay for monitoring important electrical parameters in systems. It has the dimensions 15 x 10 x 5 cm and weighs 0.13 kg. Monitoring relays are used to detect electrical quantities such as voltage, current, phase sequence, or temperature and to initiate appropriate protective measures in case of deviations. They contribute significantly to error prevention and increased operational safety. Typical applications are found in mechanical engineering for securing motors and drives, and in building automation for monitoring power supplies and emergency power systems.
