Mitsubishi Car-Top Interface Board P231702B000G01 P231704B000G01

Mitsubishi Car-Top Interface Board P231702B000G01 / P231704B000G01 is used in Mitsubishi elevator car-top, door machine, and interface signal applications.

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

• Mitsubishi Elevator Car Top Interface Board
• Mitsubishi Elevator Roof Power Board
• Mitsubishi Door Interface Board
• Mitsubishi HOPE Door Machine Power Board
• Mitsubishi GPS Elevator Door Interface Board
• Mitsubishi Elevator PCB Board

These boards are usually related to the car-top electrical area, where the elevator door machine, door interface signal, wiring harness, and controller connection may be arranged together. For replacement, the exact printed board number should be confirmed before ordering.

Model References for This Page

This page can naturally cover the following model references:

• P231702B000G01
• P231704B000G01
• DOR-525A
• DOR-530A
• P231706B000G01

Public supplier information describes P231704B000G01 as a Mitsubishi elevator roof power board and car top interface board. Other market listings connect P231702B000G01 with DOR-525A / DOR-530A as Mitsubishi GPS elevator door interface board references. P231706B000G01 also appears in the same Mitsubishi door machine interface board category, so it can be used as a related search reference, not as a direct replacement.

Why These Boards Need Exact Label Matching

Car-top interface boards may look similar, but their connector layout and wiring definition can be different.

A technician may call this part a roof power board if it is installed near the car-top power area. Another buyer may call it a door interface board if it connects with the door machine circuit. A supplier may describe it as a GPS door interface board depending on the elevator system.

These different names can point to a similar application area, but the final replacement should still depend on:

• the printed PCB model
• connector quantity and direction
• car-top installation position
• door machine wiring
• elevator system type
• old board photos

What Buyers Should Confirm

Before supply, it is better to provide:

• clear photo of the P231702B000G01 or P231704B000G01 label
• front and back photos of the PCB
• connector area photo
• car-top installation photo
• door machine or HOPE door operator photo if available
• whether DOR-525A or DOR-530A appears on the old board or system document
• existing fault description from the maintenance technician

If the old board label is unclear, a photo of the whole car-top control area is often more useful than only providing the elevator model.

Door and Car-Top Signal Notes

This type of board may be checked when the elevator has car-top signal problems, door interface faults, abnormal door machine response, wiring interface damage, or visible PCB failure.

However, the fault may not always come from the board itself. The door operator board, door motor, encoder feedback, car-top wiring harness, connector oxidation, power supply condition, and related controller input should also be inspected before confirming the PCB fault.

For overseas buyers, matching the exact board number first and checking the connector layout second is the safest way to avoid wrong supply.
