Relay modules are widely used in various electrical control systems, such as home lighting systems, motor control systems, temperature control systems, etc. The following are common application scenarios for relay modules:
- Lighting control: Relay modules can be used to control the on/off of light bulbs, streetlights, billboards, etc. By using sensors, timers, and other devices, automatic control of lighting can be achieved, improving energy efficiency.
- Motor control: The relay module can be used to control the start stop, forward and reverse rotation of the motor. Accurate motor control can be achieved by controlling the speed and direction of the motor.
- Electric heater control: In the temperature control system, relay modules can be used to control the on/off of the electric heater. When the temperature reaches the set value, the relay module will automatically turn off the electric heater to achieve temperature control.
- Security system: Relay modules can be used to control the on/off of devices such as cameras, alarms, and access control systems. By using sensors, password locks, and other devices, it is possible to control and protect the security system.
- Industrial automation: In industrial control systems, relay modules are widely used in the control, signal isolation, fault protection, and other aspects of mechanical equipment.
