Information About 440R-D22R2

Simplify installation and safety control system complexity with the 440R DI/DIS Guardmaster Safety Relays by Rockwell Automation. These units consolidate the functionality of two safety relays into a convenient single 22.5 mm housing electromechanical relay (DI) or solid state (DIS) outputs.

With the Guardmaster family of safety relays, many important components in a control system such as safety interlock switches, pressure sensitive safety mats, emergency stop devices, and OSSD devices such as safety light curtains are compatible with the same relay without added configuration, saving you time and money. These 440R DI/DIS Safety Relays help you to minimise downtime through reliable, fast fault detection which prevents risk of damage to machinery and protects personnel from injury.

These units can replace a pair of the following Guardmaster safety relays: MSR127, MSR131, MSR142, MSR144, MSR30.
