Main Board Identification and Connector Layout

The pictured assembly features eight metal-shielded connector sockets arranged in four stacked pairs along one edge. A long black multipin connector sits near the opposite edge. Compare these positions, the PCB outline, and the mounting holes with your existing board.

An upright display daughterboard carries two seven-segment digits and a blue rotary selector. Its identification is separate from the main PCB. Use the main board markings RJ311-01 / RJ311D-01 / BN634A631G51A when requesting a replacement.

Product Scope

This listing covers a PCB assembly. Confirm whether your quotation includes the display daughterboard and any accessories. The supplied configuration and fitted components will be specified in your quotation and actual-unit photos.

Fitment Confirmation

Send clear photos of both sides of your original board, all identification labels, and the equipment nameplate. Include any fault or alarm details. Match the complete identification, including the -01 suffix, and confirm the required configuration before ordering.
