The AB 440R-S13R2 is a single-input safety relay by Rockwell Automation. It is designed to provide reliable monitoring of safety devices in industrial applications. With a single input, it can be connected to various safety devices such as emergency stop buttons, safety interlock switches, light curtains, and safety mats.

The 440R-S13R2 safety relay features two normally open (NO) and one normally closed (NC) outputs, allowing for flexible safety circuit designs. It has an integrated auxiliary output for status monitoring and diagnostics. The relay is easily configurable with DIP switches and provides LED indicators for power, input status, and output status.

This safety relay complies with international safety standards, including ISO 13849-1 and IEC 61508, and is suitable for use in applications requiring functional safety. It offers robust protection against short-circuits, overvoltage, and wiring faults to ensure safe operation and protect machinery and personnel.
