Schmersal SRB301LC-24V Safety Relay

Schmersal SRB301LC-24V Safety Relay is a compact DIN-rail module that consolidates three independent safety contact channels and a single signaling output for machine guarding systems. It operates from 24 V AC/DC and is designed to interface with safety devices such as door interlocks and safety light curtains, providing three safety contact pairs (13-14, 23-24, 33-34) plus one signaling contact to relay status to the controller. The module is 22.5 mm wide, suitable for DIN-rail mounting, and carries IP40 protection, making it a practical fit for standard control panels. It supports an automatic reset function, enabling the safety circuit to re-arm automatically after a fault condition is cleared. The SRB301LC-24V is listed under Schmersal part number 101163475 and is part of the SRB301LC family designed for safe, monitored outputs in multi-channel safety applications. Typical uses include integrating multiple monitored safety sensors into a single safety controller, enabling compliant safeguarding of machinery and guarding systems in industrial environments.
