B&R X20SO4120 Safety Digital Output Module

Product Description

B&R X20SO4120 is a 4-channel Type A safe digital output module in X20 SafeIO family for B&R X20 distributed control system. It features current monitoring. OSSD safety output response time is less than 500μs, certified up to SIL3 / PL e, Category 4. It is used for safety circuit control such as emergency stop, safety gate and safety limit switches for safety-related machinery. Hot-swap supported, with onboard LED status and channel diagnostic. It must work with X20 safety CPU and safety bus base, serving as core safety I/O for machine automation safety control systems.
