Why Choose the Lovato SRCES31S Safety Relay?
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.
