Why Choose the Lovato SRCES31 Safety Relay?
The Lovato SRCES31 is a compact single-function safety relay designed specifically for emergency-stop monitoring in industrial machinery and automation systems. Part of the Lovato SRC safety relay series, it provides 3NO + 1NC safety outputs using voltage-free, forcibly guided relay contacts for dependable safety-related machine control.
Designed for safety applications up to Category 4 and Performance Level e (PLe) according to EN ISO 13849-1, the SRCES31 provides two input channels for monitoring emergency-stop circuits. Its dedicated single-function architecture makes it a practical choice where reliable emergency-stop monitoring is required without the additional configuration associated with multifunction safety controllers.
The SRCES31 operates from a nominal 24 V AC/DC auxiliary supply with an operating range of 20.4–26.4 V AC/DC. Screw terminals and standard 35 mm DIN rail mounting simplify installation within industrial control panels, while the four safety contacts provide flexibility for switching multiple safety-related circuits.

Reliable Emergency-Stop Monitoring for Industrial Machinery
Safety relays form an important interface between emergency-stop devices and the safety-related switching elements of industrial machinery. The Lovato SRCES31 monitors a two-channel emergency-stop circuit and provides multiple forcibly guided safety contacts for controlling downstream equipment as part of an appropriately designed safety system.
With three NO and one NC safety contacts, the SRCES31 provides additional switching flexibility for machinery requiring several safety-related output circuits. Its dedicated emergency-stop function, 24 V AC/DC supply and DIN rail format make it particularly suitable for machine builders and panel builders implementing conventional hard-wired safety architectures.
Typical Applications
- Emergency-stop monitoring circuits.
- Industrial machine safety systems.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Material handling and conveyor systems.
- Machine tools and manufacturing equipment.
- OEM machinery and safety control panels.
- Hard-wired industrial safety circuits requiring multiple safety outputs.
