SM 155 Series, Monitor - Relay Output

Relay output monitors are essential devices used to detect and respond to abnormal output from industrial relays. These monitors play a critical role in ensuring the smooth and safe operation of industrial systems by triggering logical outputs or a set of contacts in response to detected anomalies. There are various types of abnormal output that relay output monitors can detect, including AC and DC current or voltage variations, voltage asymmetry, ground faults, temperature abnormalities, phase loss, and sequence or imbalance issues. By detecting these anomalies, the monitors help prevent potential damage to equipment and ensure the safety and efficiency of industrial operations. One key feature of relay output monitors is their selectability, which allows users to configure trip ranges, delay times, supply voltages, mounting types, and switch circuitry according to specific system requirements. This flexibility enables customization to suit the unique needs of different industrial applications, ensuring precise and tailored monitoring and response capabilities. In summary, relay output monitors are crucial components for detecting abnormal output from industrial relays and initiating appropriate responses to maintain the safety and efficiency of industrial systems. Through the detection of various anomalies and customizable features, these monitors are integral to the reliable and effective operation of industrial equipment and processes.
