Single Receiver 433 MHz

OverviewMain features of receiving board 1. Two independent circuits. Two learning buttons, one receiver can be coded separately with two remote controllers; 2. The output mode can be adjusted through the solder joints; the relay contact can be output with electricity through the short contact setting. Regarding code matching and clearing. Code matching method: long press the code matching button on the receiving board, let go after the light is on, press the remote control button, the two channels are paired once; the code clearing method: long press the code button switch for about 10 seconds, the operation methods of the two channels are the same, respectively Empty. About output job settings 1. The mode switching point is not short-circuited and non-locked (default shipping mode); 2. The mode switching point is short-circuited with B, self-locking; 3. The mode switching point is short-circuited with A, interlocking (only interlocking between the two relays can be realized, there is no full-off function); Wiring instructions 1. The negative terminal is the negative terminal of the 12V power supply, which is not a relay output; 2. When the short contact point A or point B is disconnected, the relay outputs the switch value, and the contact is not live; 3. When the short-circuit point A or B is connected to 12V, a 12V power supply circuit is formed between the normally open and the negative pole, and the 12V load is connected to the normally open and negative pole;
