Guardmaster Safety Relay Expansion Module (440R-EM4R2)

The Guardmaster Expansion Module Safety Relay (EM) is designed to extend the functionality of Guardmaster safety relay systems by providing additional outputs and integration flexibility. It operates as an expansion module using a Single Wire Safety (SWS) or OSSD 50mA input configuration, enabling seamless communication with compatible safety devices.

This module provides four normally open (N.O.) immediate safety outputs and one normally closed (N.C.) solid-state auxiliary output, ensuring reliable and fast response in safety-critical applications. Powered by 24V DC, it features removable terminals for simplified installation and maintenance.

Ideal for use in modular safety systems, the Guardmaster EM expansion relay enhances output capacity and flexibility without requiring complex logic configurations or additional reset functions.
