Source the Mitsubishi RJ121C power PCB from REACO CNC for a matched servo drive repair or replacement. The photographed board carries PCB number BN634A549G52. Send the original drive nameplate and complete board labels so we can confirm the required assembly configuration before quoting.

Product Scope

The photos show the board from both sides, including terminal blocks marked TE1, TE2 and TE3, power connection openings and the transformer/relay area. Several outlined IC and module positions are unpopulated. Confirm the required components and any separately mounted power modules in the quotation; the photos alone do not establish a complete power-stage assembly.

Source-Checked Details

A specialist repair reference lists RJ121C-1010A / BN634A549G52 as a power board in a Mitsubishi MDS-A-V2-1010 servo drive. This is a reference for the board family, not confirmation of the photographed unit's suffix or compatibility. Electrical ratings for the complete drive should not be treated as specifications for this PCB.

Fitment Confirmation

Match the complete RJ121C suffix, BN634A549G52, revision labels, terminal arrangement, connector positions and fitted components against the original board. A shared PCB number or similar layout alone does not confirm interchangeability. The suffix label in the supplied photos is too faint to identify reliably.

For a quotation, send clear label photos, both board faces, the original drive model, fault information, quantity, preferred condition and delivery country. REACO CNC will confirm the proposed supply scope, testing details and dispatch estimate.
