Mitsubishi RK112A-12 Servo Drive Control PCB, identified by board number BN634A980G51, is available from REACO CNC for CNC servo drive maintenance and replacement. This listing offers a used board with a fitted display daughterboard, pre-shipment testing video and a 3-month warranty.

Mitsubishi RK112A-12 Product Information

Product Scope

The product photos show the populated RK112A-12 control board with its attached display daughterboard and connector assemblies. Confirm the included fittings and daughterboard with the quoted unit. This listing covers the PCB assembly rather than a complete servo drive.

Board Identification

Use RK112A-12 and BN634A980G51 as the main identification references. The photographed assembly also carries BN634A980H01 and a separate C label. Compare these markings together with the connector layout and fitted daughterboard when selecting a replacement.

Fitment Confirmation

Send the original drive nameplate and clear photos of both sides of your board. Match the complete -12 suffix, revision labels, connector keying and any firmware or configuration labels. A shared BN634A980G51 number alone does not establish interchangeability with other RK112A versions.

Record the original rotary-selector positions before removal and confirm the required settings for the host drive. Photo settings should not be used as installation instructions.

Testing and Order Support

REACO CNC provides a testing video before dispatch. Contact us with the required quantity, fault information and delivery country to confirm the actual board, test scope and shipping estimate.
