B&R X20PS9400 Supply module for bus controller

Buy online your B&R X20PS9400 Supply module for bus controller from our UK e-store Cnc-shopping UK, specialist in CNC machine-tools spare parts.

The B&R AUTOMATION X20PS9400 is a compact X20 Series power supply module designed to power the bus controller and its associated I/O segment within modular B&R automation systems. It provides stable power for the controller electronics and field I/O, making it a reliable replacement module for CNC machines, packaging equipment, robotics, and industrial automation systems built on the B&R X20 platform.

Installed alongside an X20 bus controller, the X20PS9400 accepts a 24 VDC control cabinet power supply and distributes regulated power to the backplane electronics and connected I/O modules. It supplies the bus controller, the X2X Link, and the internal I/O power system, ensuring reliable operation of the entire X20 station. Integrated status indicators allow maintenance personnel to quickly verify power availability and diagnose rack-level power issues without intrusive electrical testing.

Designed specifically for the B&R X20 platform, the X20PS9400 maintains the standard X20 slice form factor and connector layout, allowing straightforward drop-in replacement without modifying existing wiring. The bus controller and X2X Link power supplies are electrically isolated for improved system protection, and multiple power supply modules can be operated simultaneously to provide redundant bus controller and X2X Link power for applications requiring increased system availability.

The module also features an integrated RS232 service interface, simplifying maintenance, diagnostics, and commissioning procedures. Manufactured in Austria, the X20PS9400 is built for continuous industrial operation in electrical control cabinets exposed to vibration, electrical noise, and demanding environmental conditions. It is widely used in CNC machine tools, robotic systems, packaging machinery, assembly equipment, and material handling systems utilizing B&R X20 PLC technology.

Ready to replace your defective B&R AUTOMATION X20PS9400 Power Supply Module, this unit is an ideal solution for controller resets, power instability, bus communication faults, or I/O undervoltage alarms. Installing the identical model preserves the existing rack architecture, wiring layout, and system configuration while minimizing machine downtime.

Each module can be supplied as a fully tested replacement, inspected by experienced engineers on dedicated B&R X20 test benches to verify power regulation, X2X Link operation, and status indicator functionality before shipment. Supplied with a warranty, the module is carefully packaged in ESD-safe, shock-resistant materials for secure international transportation. CNC-Shopping also offers repair services, exchange programs, refurbished units, and sourcing solutions for obsolete B&R AUTOMATION components, helping maintenance teams minimize downtime and extend the service life of legacy industrial automation systems.

Frequently asked questions about X20PS9400:

Is the X20PS9400 a drop-in for my existing B&R X20 rack?
It is designed for X20 bus controller segments. Confirm your rack uses an X20 bus controller and verify total load based on module count and connected field devices to ensure proper sizing.

What input supply does this module expect?
It is intended for the standard 24 VDC control supply used in B&R X20 control cabinets. Always check the label on your installed unit or the official datasheet for exact electrical ratings.

Does replacing this module require any program changes?
No, it is a hardware power slice. Replacement is a mechanical and electrical operation, not a software task, provided you swap like-for-like and follow your site’s wiring and safety procedures.

Do you support repair or exchange for this reference?
Yes, depending on condition and inventory we can offer repair service or an exchange service to speed up the return to service while controlling costs.
