Allen Bradley's 440R-S12R2 is a safety relay that serves as a critical component in safety circuits. This device features a dual channel universal input that allows for a single input setup. With two normally open (N.O) safety outputs, it ensures reliable operation for safety-related functions within machinery and equipment. Additionally, it integrates one normally closed (N.C) solid-state auxiliary output ensuring compatibility with various control functions.

The relay operates on a 24 VDC power supply, maintaining a power consumption level of 2.5 watts, which allows efficient functioning without excessive energy requirements. The output from terminal X2 is capable of delivering a single wire safety signal or an OSSD with capabilities up to 50 mA, allowing for straightforward integration into safety applications. However, please note that terminal X1 input is not available for this model.

As safety is paramount, this relay does not support delayed safety outputs; it is designed for immediate response in all scenarios. The reset capability is a configurable feature, accommodating both automatic/manual resets or a monitored manual reset, providing flexibility based on the application requirements. The use of screw terminals facilitates easy wiring and installation, making it practical for diverse setups. Overall, the 440R-S12R2 is designed to enhance operational safety while simplifying the integration of safety measures in various environments.
