B&R Industrial Automation X20PS9400 Power Supply Module

The X20PS9400 is a dedicated 24 V DC power supply module for the B&R X20 system that provides the bus controller, X2X Link supply, and internal I/O power from a single module, helping to consolidate power architecture in compact automation installations. It is designed specifically for the X20 family and is listed as X20PS9400 with hardware upgrade paths in B&R’s product catalog, ensuring compatibility with X20 base and add-on modules. The unit accepts a 24 V DC input with a tolerance of -15% to +20% and offers a rated output current of approximately 0.7 A at 24 V DC, delivering a compact, reliable power source for the X20 bus and I/O circuitry. This power module is typically employed in modular control panels and machinery where a stable 24 V supply is required for the bus controller, the X2X link, and the I/O subsystem, enabling clean, centralized power for X20-based automation architectures. By pairing the X20PS9400 with the X20 system’s base components, engineers can build scalable, maintainable controls for applications ranging from packaging lines to conveyor systems and small-to-medium manufacturing cells, all while adhering to BR’s documented electrical specifications and hardware upgrade pathways.
