This remote switch allows you to remotely control any 12 Volt DC device. Perfect for controlling any 12V devices such as Lights, Fans, Landscaping Lighting and more. This easy-to-wire kit is perfect for anybody with a basic knowledge of electrical wiring, and can easily be wired to many 12V applications. For PC Modders, the end of result of the Remote Control 12VDC kit is truly impressive and is sure to impress the crowds. For DIYers, the kit will give some magical effect to your projects. 
 
Encoding and Decoding

The popular link is like this: MCU -> Encoder -> Transmitter ------ Receiver -> Decoder -> MCU, 
PT2262(Encoder) are optional, their existence is to 1)avoid confusing when multiple RF links in range 2) isolate disturbance.
You can integrate the encoding and decoding work to the MCUs on both side. Whenever there is no 433.92MHz devices around, you may use it as direct cable connection.

Technical indicators:

1.operating voltage: DC 12V ;       

2.static operating current:≤6mA;

3.Working temperature :-20°C- +80°C;        

4.Receive sensitivity:≥-105dBm;

5.the working frequency:433.92MHz ;
6.output current:≤10A;

7.size:74.5*54.5*27mm ;

8: Momentary Mode ,Latch Mode  , Toggle Mode can be adjustable by jumper .
9. Pls connect the receiver modules properly before power supply ;
10: 4 chanels;
11: Learning function (can works with EV1527 and PT2262 remote , can store 16 pcs different code remote );
12: Max load : 1000W;  
 
Advantage :
1:  Receiver Mother board have a learning key , if the remote is lost , must buy EV1527 Learning remotes to re-learn;

Output:

A.singnal Inter-locking (Latch)----connect 1  and 2 ;

B.singnal Self-locking (Toggle) ---- connect 2 and 3 ;

C.singnal Non-locking (Momentary ) ---- disconnect the jumper ;

 
Inter-locking (Latch): 4-way relay each other to switch, when relay A  is working and locked  ,  relay B C D corresponding to switch off; when B is working and locked , corresponding relay A C D swith off ; Only 1 relay is on among 4 relays A B C D;
 
Non-locking  type (Momentary): Press A and hold it , then A is on.Same as Relay B C D ;
 

Self-lock type (Toggle): 4 chanels opens and closes independently, 4 chanels can work together ,they don’t affect each other . press A button, A relay of work and locked, press again then  disconnected; Same as B C D .

 

Learning method and steps

1.       Press any key on remote control within 5 seconds , LED flash 3 times and then turn on , then it have success in learning .

Clear the deposit information

Keep Pressing Learning Key , LED turns off , Wait 10 Seconds , LED turn on , that deposited information has been successfully cleared ;
