Main Board and Connector Identification

The pictured RK811 assembly has four metal-shielded connectors arranged in two stacked pairs, plus a long black multipin connector along the opposite edge. The reverse-side connector markings include CN1A, CN1B, CN2, and CN3, providing useful reference points when comparing your existing PCB.

An upright display daughterboard carries two seven-segment digits and a blue rotary selector. Check its identification separately from the main board number BN634A850G51 when confirming the required assembly.

Product Scope

Confirm whether your quotation includes the display daughterboard and any accessories. The supplied main PCB, attached components, and included parts will be specified in the quotation and actual-unit photos.

Fitment Confirmation

Send clear photos of both sides of your original board, its complete labels, and the drive nameplate. Include any fault or alarm details. The additional RK611A marking is an identification reference on the photographed PCB; replacement suitability requires checking the complete assembly and original equipment details.
