High-quality New Elevator Spare Parts Printed Circuit Board Motherboard Elevator Control Board Elevator Motherboard With Elevator Inverter And Motor Model DOC-220

In-car command processing and registration: Receives and stores in-car floor selection button signals, prioritizes and memorizes commands, and coordinates with the collective control logic to schedule elevator operation, adapting to the different load and speed requirements of passenger, freight, and medical elevators.
Floor display and status feedback: Drives the in-car digital/dot-matrix floor display, synchronizing information such as running direction, stopping status, and fault codes; provides feedback on command registration, overload/full load, and door status through indicator lights, enhancing human-machine interaction.
Communication hub function: Interacts in real-time with the elevator main control board (such as the DOC-XXX series main board) via a dedicated bus to exchange operating commands, position data, and fault information, reducing shaft wiring and ensuring stable and reliable signal transmission.

Safety Circuit Monitoring and Interlocking: Collects safety contact signals from car door locks, safety gears, and speed governors; immediately cuts off the control circuit and reports faults in case of abnormalities; interlocks with the door machine controller to implement door opening and closing logic, and provides door machine protection based on door lock status.
Auxiliary Function Control: Drives loads such as car lighting, fans, and emergency power supply; supports switching control of emergency lighting and alarm devices, improving operational comfort and emergency response capabilities.
