Bridgeport Controls A-023378 CNC Mill Circuit Board

Bridgeport Controls A-023378 Circuit Board is a replacement PC board designed for Bridgeport CNC milling machines. Identified by the part number A-023378, this circuit board is used to restore control-system functionality when the primary Bridgeport control module fails. Sold as a standalone circuit board, it is intended for installation in the machine’s control cabinet within Bridgeport’s legacy CNC control architecture. As part of the Bridgeport controls family, the A-023378 board interfaces with the machine’s existing wiring harness and signal paths to support standard milling operations on compatible Bridgeport models. Typical applications include replacing damaged or worn control PCBs on older Bridgeport CNC mills, performing maintenance swaps during retrofits, or keeping on-hand spares to minimize downtime. Because this is a Bridgeport-specific module, compatibility is tied to machines that were configured with Bridgeport’s A-023378-era control electronics, and users should consult the machine’s service documentation to confirm exact fitment and connector layout. When installing, follow proper electrostatic discharge precautions and refer to Bridgeport’s alignment and connector-seating guidance to ensure reliable operation. Note that the listing covers the PCB alone and does not include additional harnesses, enclosures, or auxiliary components. This part is a replacement element within Bridgeport’s control ecosystem, intended to support continued milling operations on eligible Bridgeport CNC machines.
