Baldor Reliance 57408-D Power Interface Module

The Baldor Reliance 57408-D Power Module Interface is a plug‑in interface card for Reliance AutoMax drive systems, bridging the drive controller, power module, and analog I/O in one compact unit. Housed in a protective chassis with a faceplate, it plugs into an AutoMax Storage Rack Assembly and is secured with brackets for stable operation. On the front, three RS‑232 female connectors are labeled TO POWER MODULE, TO ANALOG I/O, and TO DRIVE CONTROLLER, and four CURRENT CALIBRATION terminals provide field adjustment as documented on the module's labeling. The 57408-D variant reflects Baldor Reliance’s lineage from Reliance Electric and is designed for AutoMax PLC environments that include both control and power interfaces within the same system.
