Mitsubishi RK112A-11 Product Information

Product Scope

The product photos show the populated RK112A-11 control board with its attached display daughterboard. Confirm that the quoted assembly includes the daughterboard, rotary selector and required fittings. Compare connector orientation, mounting positions and component clearance with the original unit.

Board Identification

Use the complete RK112A-11 model and BN634A980G51 board number when selecting a replacement. The photographed PCB also carries BN634A980H01 and a separate B label. Keep these markings together with clear photos of the connector arrangement and display daughterboard for identification.

Fitment Confirmation

Match the complete -11 suffix, revision labels, connector keying, daughterboard layout and any firmware or configuration labels. A shared BN634A980G51 number alone does not establish interchangeability with RK112A-12, RK112A-22 or other variants.

Provide the original servo drive nameplate and photos of both board faces. Record the original rotary-selector position before removal and confirm the required setting using the host drive documentation.

Testing and Order Support

Contact REACO CNC with the required quantity, fault information, preferred condition and delivery country. We will confirm the actual assembly, included parts, testing scope and shipping estimate. A testing video is provided before dispatch.
