KONE KDSISCB Shaft Board KM51253838G01 KM51253839H01

KONE KM51253838G01 is a KDSISCB PCB assembly used in the shaft equipment of compatible KONE elevator systems. The circuit board may also be identified by the printed reference KM51253839H01.

In the elevator spare-parts market, this product is commonly described as a shaft board, elevator well PCB, or shaft communication board. It is supplied as an individual circuit-board assembly rather than a complete elevator controller.

Confirm What Is Installed in the Shaft

Because this board is normally identified after it has been removed from the elevator shaft, clear photos are especially useful. Dust, damaged labels, previous repairs, and similar-looking PCBs can make identification difficult from one number alone.

Please check and provide:

• KM51253838G01 assembly label

• KM51253839H01 PCB marking

• KDSISCB identification

• front and rear PCB photos

• connector quantity and location

• terminal markings

• installation position in the shaft

• controller or elevator model

• photos of the connected wiring

• quantity required

KM51253838G01 should be matched with the original KDSISCB board rather than selected only by general appearance. Another shaft PCB may use a similar housing or connector style but have a different board revision or wiring arrangement.

Before installation, technicians should inspect the plugs, terminals, shaft wiring, power supply, grounding, and nearby devices. Burnt connectors, moisture, loose terminals, or damaged cables may remain the actual cause of the fault even when the PCB has already been replaced.

The board should be installed and tested by qualified elevator personnel. All related shaft signals and elevator functions must be checked before the equipment returns to service.

For orders from Saudi Arabia, Jordan, Egypt, Iraq, Syria, UAE, Brazil, Peru, Spain, and Italy, sending one photo of the complete installed area together with close-up label photos usually provides enough information for preliminary matching.
