ABB 1SVR730841R1300 Industrial Safety Relay Module

ABB 1SVR730841R1300 CM-SRS.12S Current Monitoring Relay is a single-phase DIN-rail module that monitors the current in the live conductor of an AC circuit and provides a single changeover (SPDT) output. It operates from a 220–240 V AC supply and senses currents in the 0.3–15 A RMS range, enabling a discrete indication of whether the line current stays within that band. The device belongs to ABB's CM-SRS family of current monitoring relays, with the 1SVR730841R1300 order number designating the 12S variant. Its compact DIN-rail form factor supports quick panel mounting in automation and control-safety applications, where the monitored current state can be signaled to PLC inputs or signaling relays as part of a safety or control interlock scheme.
