B&R Industrial Automation X67UM4389-C01 Power Supply

The B&R X67UM4389-C01 Power Supply is a 24 V DC power-supply accessory for the B&R X67 modular automation system, designed to be installed within an X67 backplane-equipped cabinet to provide a stable, centralized source of 24 V for the X67 family of I/O modules and field devices. As a dedicated supply accessory in the X67 lineup, it supports the backplane voltage distribution that enables reliable operation of connected I/O channels and interface components, helping to maintain consistent performance across the automation network. The part number X67UM4389-C01 and its classification in distributor catalogs confirm its role as a power-supply component within B&R's X67 ecosystem rather than a controller or signal-processing module. Typical applications include industrial control cabinets where multiple X67 I/O modules require a centralized 24 V rail, such as machine automation, packaging lines, and process control systems. When integrating, verify compatibility with the X67 backplane and use appropriate harnessing to ensure clean power delivery across connected modules and field devices.
