The Lovato SRCES31S is a compact single-function safety relay designed for emergency-stop monitoring in industrial machinery and automation systems. Part of the Lovato SRC safety relay series, it provides a 3NO + 1NC contact configuration with forcibly guided relay contacts for dependable safety-related machine control.
Designed for safety applications requiring reliable monitoring of emergency-stop circuits, the SRCES31S uses two input channels and provides multiple output contacts for interfacing with downstream machine-control equipment. The relay is designed for safety systems up to Category 4 and Performance Level e (PLe) according to EN ISO 13849-1, subject to the architecture and configuration of the complete safety system.
The SRCES31S operates from a nominal 24 V AC/DC auxiliary supply and is distinguished by its spring-clamp terminals, which provide fast, secure conductor connection without conventional terminal screws. Standard 35 mm DIN rail mounting makes the relay suitable for compact industrial control panels and OEM machine installations.

Reliable Emergency-Stop Monitoring for Industrial Machinery
Safety relays provide the monitored interface between emergency-stop devices and the switching elements responsible for bringing hazardous machine functions to a safe state. The Lovato SRCES31S is designed for two-channel emergency-stop monitoring and uses forcibly guided relay contacts to provide dependable safety-related outputs.
With three NO and one NC contacts, the SRCES31S provides flexibility for machine designs requiring several safety-related switching or monitoring functions. Its spring-clamp terminal technology also simplifies control-panel assembly and maintenance by providing secure conductor connections without traditional screw tightening.
