The 1SVR740841R0400: As a DIN-rail mounted relay, it integrates into standard control panel enclosures alongside contactors and terminal blocks. The CM-SRS.21P monitors current on a single phase and provides a relay output when the measured value crosses the adjustable threshold — common for conveyor jam detection, pump dry-run protection, or heater failure alarms.
