Connection with other control boards |
The relay board is connected to other control boards (such as the main control board, door machine control board, etc.) through wires or other connection methods, receives commands and signals from these control boards, and feeds back the operating status of the elevator. |
|
Execute control instructions |
According to the received instructions and signals, the relay board drives the elevator's motor, brake, door machine and other components by controlling the opening and closing of the relay, thereby realizing various operating states of the elevator. |
The relay board is an electronic control board that uses relays (an electrical control device) to open and close the circuit and switch it. In the elevator system, the relay board is mainly used to control the various operating states of the elevator, such as starting, accelerating, decelerating, stopping, and opening and closing the door.
Application of relay board in elevator
● Controlling elevator operation: The relay board receives instructions from the elevator control system and drives the elevator's motor and brake components by controlling the opening and closing of the relay, thereby realizing the elevator's up and down operation and parking.
● Achieving safety protection: The elevator system is equipped with a variety of safety devices, such as door locks, speed limiters, safety clamps, etc. The relay board can monitor the status of these safety devices and cut off the power source of the elevator when an abnormal situation is detected to ensure the safety of passengers and elevator equipment.
● Display and signal control: The relay board is also responsible for controlling the display devices inside and outside the elevator, such as the floor display in the car, the direction indicator, and the call button outside the hall door. These display and signal devices provide passengers with intuitive information on the elevator's operating status.
The elevator control system is a complex electronic system, which includes multiple control boards, sensors, actuators and other components. As a part of it, the relay board works with other control boards to realize the automatic control of the elevator
The relay board plays a vital role in the elevator system. It is not only an important part of the elevator control system, but also responsible for controlling the various operating states of the elevator and realizing safety protection and other functions.
