B&R Industrial Automation X67UM4389 Power Supply Module

The B&R X67UM4389 power supply module (Rev H0 I) is a dedicated power supply accessory for the X67 I/O system, designed to feed the X67 backplane and its connected I/O modules through the X2X Link, consolidating power distribution in a compact form factor. Weighing about 0.64 lb, this part carries the model number X67UM4389 and is cataloged as a Power Supply Module / Power Supply Accessory for the X67 series; distributor listings also note it as discontinued by the manufacturer, which can affect availability and replacement planning. As an integral component of legacy X67 configurations, the module coordinates with X67 I/O modules and uses the X2X Link for interconnectivity within B&R automation networks, with Rev H0 I identifying its revision level within the product family. While sourced through distributors that mark it discontinued, the X67UM4389 remains compatible with existing X67 installations, making it a relevant option for maintenance, repair, or decommission planning in facilities that still deploy the X67 architecture.
