This listing covers the replacement circuit board assembly shown. Confirm the full board number, revision and original CNC configuration before selecting a replacement.

WN763 Product Information

Product Scope

The supplied photos show both sides of the WN763 board, including the logic circuitry, memory devices, edge connectors, card slot and onboard power components. Visible interface labels include LAN1, LAN2, SIO, SKIP, ENC, LCD, ADCPU and FRONT. Compare their positions and connector keying with the original assembly.

Source-Checked Details

Mitsubishi's Data Acquisition Unit User's Manual, IB-1501548-B, section 2.2.1, shows WN763/764 as base cards with 512 MB DRAM in the M80 connection diagram. This is a DRAM specification; available machining-program storage and enabled CNC functions depend on the complete system configuration.

Fitment Confirmation

Provide the CNC control-unit nameplate, the original board's complete markings and clear photos of both sides. Match WN763, BN638A991G52, revision labels, fitted components and connector arrangement. Confirm the required system software and machine-builder configuration for the replacement unit.

Before removal, have a qualified technician back up the machine data and record the installed cards and switch positions. Confirm which memory cards, data, software and accessories are included in the quotation, including whether the card visible in the photos is supplied.

Send the required quantity, preferred condition and delivery country for a quotation. Actual-unit photos, the testing scope, a pre-shipment test video and dispatch timing can be confirmed before shipment.
