B&R Automation X20PS9400 Power Supply Module for X20 System

The B&R Automation X20PS9400 (X20PS9400) is a dedicated power supply module designed for use within the modular B&R X20 control and input/output system. Operating as an essential power feed component, this module supplies electrical power to the internal X20 communication bus and connected I/O slice modules across the backplane. It integrates directly onto the standard X20 terminal block and base, enabling seamless power distribution inside industrial automation control cabinets without the need for extensive external wiring. Designed for demanding automation environments, the X20PS9400 supports reliable system operation across packaging machinery, material handling systems, assembly lines, robotics cells, and continuous process control applications. It ensures stable power delivery to local expansion racks, remote I/O stations, and field devices operating under standard 24 VDC industrial control voltages. By maintaining voltage stability and bus power continuity, this power supply module protects downstream I/O hardware and supports dependable machine performance during routine operations, maintenance overhauls, or full system retrofits.
