Function and Positioning

The X20SO4110 functions as a safety-critical output interface in automated systems, enabling direct control of safety actuators such as relays, valves, and contactors up to SIL 3 / PL e levelsB& R Industrial Automation. Its Type A (high-side + low-side) switching allows safe de-energization of actuators in all fault conditions, preventing unintended restartB& R Industrial Automation. Integrated current monitoring and open-circuit detection provide continuous diagnostics, while thermal shutdown protects against overloads and short circuits. Positioned for high-availability machine safety and process safety applications, it integrates seamlessly with B&R’s X20 PLCs and safety controllers via X2X Link for synchronized safety logic executionB& R Industrial Automation.
