Allen-Bradley 440R-D22R2 | Guardmaster Dual Input Safety Relay
Overview
The Allen-Bradley 440R-D22R2 is a Guardmaster dual input safety relay designed to monitor safety devices such as emergency stop buttons, safety gates, and light curtains. It features two dual-channel universal inputs and provides two normally open (N.O.) safety outputs along with one normally closed (N.C.) auxiliary output. The relay supports configurable logic (AND/OR) and can be set for automatic, manual, or monitored manual reset modes.
