Allen-Bradley 440R-EM4R2
Overview
The Allen-Bradley 440R-EM4R2 is a Guardmaster safety relay expansion module designed to increase the number of safety outputs in a system. Operating at 24V DC, it provides four normally open (N.O.) safety outputs and is intended for use with base safety relays that support single-wire safety (SWS) connections. Its compact design and IP40 enclosure rating make it suitable for various industrial applications.
