B&R Industrial Automation X20SO4110 Safety IO Module

X20SO4110 is a 4‑channel safety output module for B&R's X20 SafeIO system. It provides four safe type A digital outputs with per‑channel current monitoring for safe actuation of machinery in safety‑critical applications. Operating from a 24 V DC supply, each channel is rated for 0.5 A and delivers an OSSD (output safety signal device) signal with a response time of under 500 microseconds, enabling fast safe shutdown or enablement in safety circuits. The module uses semiconductor‑based output technology to keep safety characteristics independent of switching cycles and is designed for integration on the X20 bus backplane, communicating over the X20 SafeIO network to pair with B&R safety controllers and other X20 modules. The X20SO4110 is listed as revision M0 in product documentation. This module is suitable for use in safety‑related tasks such as safeguarding devices, emergency‑stop circuits, and controlled safety actuators within an automation system.
