Mitsubishi RK311 Product Information

Main Board Identification and Interface Layout

The pictured RK311 assembly has eight metal-shielded connector sockets arranged in four stacked pairs along one edge. A long black multipin connector with retaining clips sits along the opposite edge. These features, together with the PCB outline and mounting holes, provide useful visual matching points.

An upright display daughterboard carries two seven-segment digits and a blue rotary selector. Check its identification separately from the main PCB number BN634A817G51. The main board close-up also shows an RK311B- marking; confirm any additional suffix from your original 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 your quotation and actual-unit photos.

Fitment Confirmation

Send clear photos of both sides of your existing board, all identification labels, and the equipment nameplate. Include any fault or alarm details. Match the complete board identification and connector configuration before ordering.
