Mitsubishi Interface Board P231720B000G01

Mitsubishi Interface Board P231720B000G01 is a car-top interface PCB board used in Mitsubishi elevator systems.

In the elevator spare parts market, this board is commonly described as:

• Mitsubishi Car Top Interface Board
• Mitsubishi W1 Interface Board
• Mitsubishi Elevator Interface PCB
• Mitsubishi Elevator Car-Top PCB Board
• Mitsubishi Elevator Control Signal Interface Board

This type of board is usually installed around the elevator car-top control area, where signal connection between the elevator controller, car-top wiring, door system, and related control circuits may be arranged.

For this product, the exact PCB version should be confirmed carefully before ordering.

P231720 Series Model References

This page can naturally cover the following model references:

• P231720B000G01
• P231720B000G02
• P231720B000G11
• P231720B000G12

Public supplier pages commonly list these four versions together as Mitsubishi elevator car top interface board or W1 interface board models. These references are useful for product search and quotation confirmation, but they should not be treated as automatically interchangeable without checking the old board.

Why This Board Should Be Matched by Version

P231720B000G01 may look similar to other P231720 series boards, but different suffixes can indicate different board versions, connector layouts, or wiring configurations.

A buyer may search for P231720B000G01, while a technician may describe it as a W1 interface board or car top interface board. These names may refer to the same board family, but the final replacement should still depend on the original PCB label and installation position.

For real supply confirmation, technicians usually check:

• Complete P231720B000G01 / G02 / G11 / G12 marking
• Front and back photos of the PCB
• Connector quantity and direction
• Car-top installation position
• Nearby door operator or control wiring
• Elevator system information if available
• Existing fault description from the maintenance technician

Where This Board Is Usually Checked

A car-top interface board may be checked when the elevator has signal connection problems around the car-top area.

Possible site issues may include:

• abnormal car-top signal response
• interface communication problem
• door system signal interruption
• car-top wiring fault
• connector oxidation
• visible PCB damage
• unstable control signal between car and controller

These symptoms may not always be caused by the board itself. The car-top wiring harness, door operator board, connector terminals, power supply condition, and related controller inputs should also be checked before confirming the PCB fault.

Practical Supply Note

Do not select P231720B000G01 only by appearance.

For overseas buyers, matching the exact board version is the safest method. If the old board label shows P231720B000G02, P231720B000G11, or P231720B000G12, please provide a clear label photo before ordering.

A complete car-top installation photo can also help confirm whether the required product is P231720B000G01 W1 Interface Board or another Mitsubishi car-top interface PCB.
