Request the Mitsubishi RJ111D11 control PCB from REACO CNC for a matched servo drive replacement. The photographed assembly carries RJ111-11 and RJ111D-11 identification, with PCB number BN634A685G51 and a separate A marking.

Product Scope and Connector Layout

The photos show a populated control board with six external connector ports arranged in three stacked pairs. A small daughterboard carries a two-digit display and blue rotary selector. Confirm that the quotation includes this daughterboard and the connectors shown. Supply scope covers the agreed PCB assembly; a complete servo drive, enclosure and power section are separate items.

Source-Checked Identification

A specialist repair reference lists RJ111D-11 / BN634A685G51 A as a control board in a Mitsubishi MDS-A-V1-45 servo drive. This supports the board classification, but replacement suitability must be checked against the original drive and board configuration. Drive voltage, current and power ratings are not PCB specifications.

Confirm the Original Board Before Ordering

Send the drive nameplate, complete PCB number, revision labels and clear photos of both board faces. Compare the -11 suffix, A marking, connector positions, daughterboard and component layout. Match firmware or memory labels where present, and record the original selector position. Shared PCB numbers alone do not establish interchangeability between different suffixes or configurations.

Contact REACO CNC with these details to confirm the quoted board, condition, test scope and delivery estimate.
