CANNY Elevator Plug-in Interface Board KLS-MAD-02A

CANNY Elevator Plug-in Interface Board KLS-MAD-02A is used in CANNY elevator control cabinet signal interface and relay-related PCB applications.

This board should not be confused with CANNY main control boards such as KLS-MCD-01A or KLS-MCD-02A. KLS-MAD-02A is more suitable to describe as a plug-in interface board, relay interface PCB, or elevator signal connection board inside the CANNY elevator control system.

In the elevator spare parts market, this product may also be searched as:

• CANNY Elevator Plug-in Interface Board
• CANNY Elevator Interface Board
• CANNY Elevator Relay PCB
• CANNY Elevator Relay Board
• CANNY Elevator Signal Interface PCB
• CANNY Elevator Control Cabinet PCB
• CANNY Elevator PCB Board

The main model reference for this page is:

• KLS-MAD-02A

Related model references may include:

• KLS-MAD-01A
• KLS-MAD-01B

These related models are useful for search coverage and quotation confirmation. However, KLS-MAD-01A, KLS-MAD-01B, and KLS-MAD-02A should not be treated as automatically interchangeable without checking the original board label, connector layout, and cabinet wiring.

Plug-in Interface and Relay PCB Application

KLS-MAD-02A is normally related to signal interface connection inside the CANNY elevator control cabinet.

Depending on the cabinet configuration, it may work with relay signal circuits, plug-in terminal connections, control signal transfer, or auxiliary interface wiring. This makes it different from a controller CPU board, display board, button board, or door operator inverter.

Technicians may inspect this board when there are problems such as:

• relay signal abnormality
• interface signal interruption
• control cabinet plug-in connection issue
• input or output signal not responding
• connector or terminal problem
• visible PCB damage
• intermittent elevator control signal fault

These symptoms may also come from wiring terminals, relay components, cabinet power supply, connector oxidation, or another control board. The complete control cabinet signal path should be checked before confirming the PCB fault.

How to Confirm the Correct Board

Before ordering CANNY Elevator Plug-in Interface Board KLS-MAD-02A, please check:

• Complete KLS-MAD-02A marking on the old board
• Whether the old board shows KLS-MAD-01A or KLS-MAD-01B
• Front and back photos of the PCB
• Connector quantity and connector direction
• Relay or terminal area photo if visible
• Control cabinet installation position
• Nearby board numbers inside the cabinet
• Existing fault description from the maintenance technician

If the old board label is unclear, a full photo of the control cabinet and close-up photos of the connector area can help confirm the correct replacement faster.

Replacement Notes

Do not select KLS-MAD-02A only by appearance.

CANNY plug-in interface boards may have similar PCB size or terminal layout, but the signal definition, relay connection, board version, and cabinet wiring may be different. Before installation, technicians should compare the old and new board carefully and check the surrounding wiring condition.

If the original board was damaged by unstable power, relay circuit fault, wiring short circuit, moisture, or connector oxidation, replacing only the PCB may not fully solve the problem.

For overseas buyers, sending clear photos of the original KLS-MAD-02A board, cabinet installation position, plug-in connector area, and nearby relay wiring is the safest way to reduce wrong supply before shipment.
