Schmersal SRB301MC-24V safety relay is a three-channel safety relay module designed to safely evaluate signals from emergency-stop devices, guard doors, magnetic safety switches and AOPDs. It is powered from 24 V (AC/DC) and provides three safety contacts plus one auxiliary contact, with automatic reset. Encased for panel mounting, it carries an IP20 rating for internal use, and is widely used to implement dual-channel safety circuits in machinery, enabling compliant safe-stop behavior and guard monitoring.
