Mitsubishi Pushbutton Expansion Board DC570A114G01

Mitsubishi Pushbutton Expansion Board DC570A114G01 is used in elevator push button signal and operating panel expansion applications.

This board is usually related to button command input, pushbutton signal extension, or elevator panel PCB connection. In the elevator spare parts market, it may also be searched as:

• Mitsubishi Pushbutton Expansion Board
• Elevator Expansion Board
• Elevator Button Board
• Push Button PCB Board
• Elevator Button Panel PCB
• Elevator Operating Panel PCB

The main model reference for this page is:

• DC570A114G01

Related model references may include:

• DC570A114G02
• DC570A114G03

These model references are useful for search coverage and quotation confirmation. However, G01, G02, and G03 should not be treated as automatically interchangeable without checking the original board label, connector layout, and panel configuration.

Button Expansion Application

DC570A114G01 should be understood as a button expansion PCB or push button board, not a single elevator button.

Depending on the elevator panel structure, it may be installed inside a car operating panel, landing operating panel, button panel, or related command input area. Its function is usually connected with button signal transmission rather than mechanical button pressing alone.

Maintenance teams may check this board when there are issues such as:

• elevator button not responding
• partial button signal failure
• button indicator abnormality
• call command not registering
• intermittent button response
• connector or wiring issue inside the panel
• visible PCB damage

These symptoms may also be caused by the button itself, panel wiring harness, connector terminals, power supply, or related communication board. The complete button signal path should be checked before confirming the PCB fault.

Model Confirmation Notes

Before ordering Mitsubishi Pushbutton Expansion Board DC570A114G01, please confirm:

• complete DC570A114G01 marking on the old board
• whether the old board shows DC570A114G02 or DC570A114G03
• front and back photos of the PCB
• connector quantity and direction
• panel installation position
• old button panel photo if available
• existing button fault description
• nearby board numbers if visible

If the old label is unclear, a full photo of the panel interior and close-up photos of the PCB marking can help confirm the correct replacement faster.

Practical Replacement Notes

Do not select this board only by appearance.

Elevator button expansion boards may look similar, but the supported button quantity, connector layout, signal definition, and board version may be different. Before installation, technicians should compare the old and new PCB carefully and check the button harness, connector oxidation, power supply condition, and related signal circuit.

For overseas buyers, sending clear photos of the original DC570A114G01 board before shipment is the safest way to reduce wrong supply.
