     It is an rf wireless 4 channel relay board that can be used with remote controls operating in 433MHz 1527 type. It is used by recording the remote control with the button on it. You can use it in your wireless control applications up to 100 meters in open area and 10/30 meters in indoor area. There is a 250V 10A relay on the product. It is suitable for use with loads up to 7A in long-term use.

If the relay works exactly the opposite of what you want, you can change its direction by moving the wire at the edge of the connections to the other edge

Usage:

1. Recording/teaching the remote control to memory: Press the button once. When the led goes off, release the button and press the button on the remote control. If the led blinks 2 times, the recording has been done successfully.
2. To delete the remote control, press and hold the button for 8 seconds. When the led goes off, the remote controls saved in memory have been deleted.
3. Test: After the recording process, the relay becomes active as the remote control button is pressed.
