a good thing if you need to remotely control any electrical circuit or device.In this article you will learn pros and cons of this device, as well as instructions on how to properly set modes.
12V Dual channel remote relay review
Before buy check my little review of this dual-channel remote controller there are pros and cons
Here is pros:
- It has a box that protects the electronics
- Good price considering the function that offers a remote-controlled relay
- Good range of remote control about 60 m
- 2 relays can control two different devices if required
Here is cons
- In the beginning it can be difficult to set a relay modes
- The remotes some vendors not give 12V A23 alkaline battery (you have to buy separately)
Detailed description of 12V dual channel remote controller :
Now i describe remote control and electronic board with relay.
Remote control have black case with two butons. Buttons A and B control individual relay on PCB.
Press buton on remote control the relay on or off (how is seting on pcb board). Red LED indicating the pressing of buttons respectively transmitted signal. To control work is necessary to ensure power supply with 12V A23 battery (It costs about 1 USD).
The instructions manual below to learn how to pair your controller with relay
Remote control board with relay
- Relay terminals
- 12V source terminal
- Green LED
- Red LED
- PCB button switch T1
- A relay and B relay
- Signal receiver
Power should be either 12V DC voltage from the transformer or battery. The illuminating green LED indicates that the device is OK.
Two relays have three terminals, COM midle terminal .NO – (Normaly open) and NC (Normaly closed). If you press on the remote control, NC opens and closes the NO. (other features based on the selected mode)

How to setup remote relay? -here is short manual
Short briefing as set your device to work properly – here is instructions:
First pair the remote control transmitter with electronic board
Connect the relay electronic board to 12V transformer and lights up green LED. Then press the button (PCB button switch T1) on the electric board for one second by pressing a button press on the remote control button first A and then B. LED on electric board indicates pairing relays with remote control keys A,B. Frequency is 314Mhz or 432Mhz (You must have the correct remote driver for the best book together with receiver )
How to setup “programing” electronic board with relay :
For proper operation of remotely controlled relay, the remote control, press the DIP switch T1 and watch the LEDs
“Operation confirmation” press T1 until a permanent red LED on the controller, then press A and then B.
MOD1 of remote relay:
Press the T1 for 2 seconds LED lights then goes out hold down until the LED flashes once then release the button T1, 2 seconds pause, and then do the operation Confirmation So you press T1 until the red LED lights up, then the remote control, press A then B
Mod1 works so that when you press the A button on the remote control relay 1 connect COM1 and NC1 outputs and relay 2 outputs connect COM2 and NO2
When you press B on the remote control relay 1 connect outputs COM1 and NO1 relay 2 NC2 and COM2 (disconect COM1 and NC1 or COM2 and NC2)
MOD2 of remote relay:
Press the T1 2 seconds LED lights then go off hold button LED will blink once then twice, release the button T1, 2 seconds pause, and then do the operation Confirmation So you press T1 until the red LED will light up on the remote control then press A then B
Mod2 works so that each relay has its control button relay 1 has a button A, Relay 2 has button B.
Press A to select the output to be connect terminals for example relay 1 NO1 COM1 and press the button again disconect the COM1 and NC1 (COM1 and NO1 recovers) Relay2 same job for B button on the remote control.
MOD3 of remote relay:
Hold button T1 2 seconds LED lights then goes out hold down the button LED will blink once then twice and finally three times, then the T1 release, two seconds pause, and then do the operation Confirmation So you press T1 until the red LED lights up, then the remote control, press A then B
Mod3 operates the A button for Relay 2 can output can Relay2 COM2 and NO2, while unfasten output and COM2 NC2 .In solid state are conects outputs and COM2 NC2. Output COM2 NO2 and remains conect only for pressing the A. For relay 1 is designed for the remote control button B.
Quick english manual:
Inching: press&hold one button, the reply turns on, release the button, the reply turns off.
Self-lock: press the one button, the reply turns on, press the button again, the reply turns off.
Press&hold the program button on the receiver, the red light will turn on and stay on for about 5 seconds.
Choose the mode:
inching:release the button after the light flashes three times.
Self-lock:release the button after the light flashes twice.
Inter-lock:release the button after the light flashes once.
Link the remote control:
Press the program button on the receiver until the red light turns on, and then release the program button, the red light will stay on.
Press a transmitter button, and the red light will flash, at this time, it means finished linking.
