Product Description: Allen-Bradley 440R-EM4R2D
The Allen-Bradley 440R-EM4R2D is an expansion module within the Guardmaster Safety Relay (GSR) family, designed to provide four delayed normally open (N.O.) safety outputs. It integrates seamlessly with other GSR units via a Single Wire Safety (SWS) connection, allowing for scalable and flexible safety system architectures. This module is ideal for applications requiring time- delayed safety outputs, such as controlled machine stopping sequences.
