Schmersal SRB-E-201ST Safety Relay Module 24V DC

Schmersal SRB-E-201ST Safety Relay Module is a configurable, 24 VDC multifunction safety relay designed to monitor safety sensors and drive safety outputs in a compact, pluggable-screw-terminal package. It provides one pair of OSSD safety outputs and a dedicated diagnostic/status output for monitoring the health of the safety chain, and it supports up to eleven configurations, enabling flexible adaptation to a wide range of safety circuits without external logic. The module draws about 2.4 W from a 24 V DC supply, and it is part of Schmersal’s SRB-E family, with variants available for different wiring schemes (including CC versions).
