DOR‑1321B is a door operator control board specially designed for Mitsubishi machine‑room‑less elevators, upgraded from DOR‑1321A. This advanced control panel fully manages door motor speed, torque, and position signals for passenger elevators.
Equipped with integrated power drive, signal acquisition, and heat dissipation modules, it supports light curtain and safety edge input. Jumpers on the board allow precise adjustment of opening and closing speed and torque parameters, enabling flexible door‑movement curve configuration.
This board serves as a key replacement spare part for elevator maintenance, offering direct replacement for damaged same‑model boards without requiring additional firmware modification, which simplifies on‑site commissioning processes.

When an elevator displays door errors, abnormal door movement, or no door output, the DOR‑1321B is one of the key components to inspect. Simultaneously, the door motor, light curtain, and external wiring should also be checked to avoid unnecessary board replacement. This control panel is widely used in commercial and residential Mitsubishi machine‑room‑less elevators, offering excellent compatibility with related door‑board series and extensive spare‑part circulation.
