The LHS-400A is the car communication PCB board exclusively designed for Mitsubishi GPS-3 elevator systems. It serves as the core signal transfer unit inside the elevator car, processing floor button commands, feedback signals, and display data between the car operating panel and the main controller. The board adopts a stable serial communication architecture and multiple plug-in terminals to ensure reliable signal transmission under the long-term vibration conditions present inside the elevator car.

This board is a critical maintenance spare part. Common failure symptoms include unresponsive car buttons, abnormal floor display, and intermittent communication loss — any of which will prevent the elevator from registering car calls normally.
The LHS-400A shares the same installation structure as the LHS-402A and supports direct replacement after a simple power-off operation. It is widely stocked for routine overhaul and fault repair of Mitsubishi GPS-3 passenger elevators.
