B&R Industrial Automation X20SO4110 Digital Safety Output Module

The B&R X20SO4110 is a four-channel safe digital output module for the X20 safety system, delivering 24 VDC outputs with current monitoring and ultra-fast response. Each safe type A output is rated for 0.5 A and includes on-channel current monitoring, with an output signal switching (OSSD) time under 500 microseconds. Designed for safety-related actuator control, the module supports safety performance up to PL e or SIL 3 and integrates into the X20 platform using semiconductor-based outputs to preserve safety characteristics across cycles. The part is listed as X20SO4110 in official B&R materials and carries a B&R ID code of 0x1DBE, confirming its role as a dedicated safe digital output module for safety-critical automation tasks.
