Mitsubishi WN323 is a CNC operation panel I/O PCB offered for replacement matching. The photographed board carries an additional WN323B marking and the board number BN638A827G51.

The populated PCB includes four tall multi-pin connectors arranged in two pairs, repeated I/O circuit groups, upright resistor-array modules and a keyboard-interface connector. Compare the full markings and fitted components with the original board before selecting a replacement.

WN323 Product Information

Product Scope

This listing covers the independent PCB shown in the photos. Confirm separately whether a front keypad, mounting frame, ribbon cable or other panel hardware is required. The quoted supply scope should identify the board and any included accessories.

Model and Board Identification

Use WN323, the photographed WN323B marking and BN638A827G51 together when requesting a quotation. A Made in Japan marking is visible on the PCB. Match the complete identification and revision labels with the original assembly.

The photos show connector labels including CJ37, CJ38, CJ39, CJ40 and NCKB. Compare connector positions, latches, keying and mounting holes. The upright component rows and repeated circuit layout provide further visual comparison points.

Fitment Confirmation

Send the original PCB markings, the operation panel I/O unit label and the CNC control-unit model. Confirm the required I/O configuration, board revision, connector arrangement, keyboard connection and installation clearance before ordering.

Where the original equipment is labelled FCU8-DX750, include that unit label with the board photos for matching. Verify the complete assembly configuration and wiring requirements; the WN323 family reference alone is insufficient to establish the required specification.

For a quotation, provide the quantity, preferred condition and delivery country. Actual-unit photos, supplied accessories, the testing scope, a pre-shipment test video and dispatch timing can be confirmed before shipment.
