Bosch Rexroth S20-PSDO-8 3 R911173255 Interface Module

The Bosch Rexroth S20-PSDO-8/3 Interface Module (R911173255) is an eight-channel PROFIsafe safe-digital output module designed for use with the IndraControl S20 family. It provides eight safe digital outputs (OSSD) that feed safety circuits and safe-actuation devices on PROFIsafe networks, enabling certified safety signals to control safety relays, interlocks, and emergency-stop functions. As an interface module in the S20 IndraControl I/O lineup, the PSDO-8/3 integrates with safety controllers to form a cohesive safety I/O system, supporting distributed safety architecture across automation cells. The module is targeted at applications requiring multiple independent, safety-rated outputs for guarding circuits, machine safety logic, and fail-safe stop conditions, while maintaining the integrity of the PROFIsafe communication channel with compatible controllers. The R911173255 designation identifies the eight-output PSDO variant within Bosch Rexroth’s IndraControl S20 safety I/O offerings, making it a suitable choice for engineers designing modular, scalable safety solutions in factory automation.
