QIACHIP12V 4 Channels Wireless Relay Remote Control Switch 433Mhz RF 10A Universal 4CH Receiver Module with 4 Transmitters Remote Controller for Lights,Garage Door,Motor,DIY

QIACHIP 12V DC 4CH Wireless Remote Control SwitchHaving bought one of these boards and reading the manual that comes with the device and also the instructions on this listing I have done some experimenting and have come up with the following to make things clearer.Power supply voltage: 9-12V DC only. I have tried it at 9 Volts and it works fine, which is good for boats using 12V batteries.The ground or - terminal is next to the learn button and the positive or + is next to GND. If you are going to be using the power supply to also power 12V DC devices then make sure your power supply has enough current output to power everything.The relay terminals are all numbered.Relay for button A: 1 is Normally Closed, 2 is Common and 3 is Normally Open.Relay for button B: 4 is Normally Closed, 5 is Common and 6 is Normally Open.Relay for button C: 7 is Normally Closed, 8 is Common and 9 is Normally Open.Relay for button D: 10 is Normally Closed, 11 is Common and 12 is Normally Open.Be aware that NO voltage comes out of these terminals by default as they are just switch contacts, if you need to switch voltage then you have to connect your voltage to the Common terminal to be able to get voltage out of Normally closed or Normally open.The listing mentions that the relays are rated at 10 Amps but I would not run 10 Amps through this board as the circuit board tracks would likely burn out.Working Modes:Momentary: When a button is pressed the relay will operate briefly but if you keep the button pressed it will keep the relay engaged until you release the button.Toggle: A single press will turn the relay on and stay on and a second press will turn it off.Latched: Not sure when you would need this but pressing button A will turn relay 1 on and pressing button B will turn off relay 1 and turn on relay 2. A and B are linked and C and D are linked this way.Clear all remotes: Press the learning button 8 times and wait 3 seconds.Do not follow the instructions on the listing page above when learning in your remotes where it tells you to press the learn button 8 times and then 1, 2 or 3 times after that as pressing the learn button 8 times will delete all remotes from the board, that will leave you with only the 1 remote working that you then learnt in by pressing 1-7 after the 8 presses.Learning remotes:1 press: Momentary: When the LED comes on press A on remote and the LED will go out. All buttons will be in momentary mode.2 presses: Toggle: When the LED comes on press A on remote and the LED will go out. All buttons will be in toggle mode.3 presses: Latched: When the LED comes on press A on remote and the LED will go out. All buttons will be in latched mode. Only one relay can be on at any time.4 presses: When the LED comes on press A on remote and the LED will go out. Buttons A & B will be in toggle mode, buttons C & D will be momentary.5 presses: When the LED comes on press A on remote and the LED will go out. Buttons A & B will be in latched mode, C & D will be momentary.6 Presses: When the LED comes on press A on remote and the LED will go out. Buttons A & B will be in latched mode, C & D will be toggle.7 presses: When the LED comes on press A on remote and the LED will go out. Buttons A & B will be in latched mode, C & D will be latched. Two relays can be on at once, either A or B plus either C or D.Each remote can be learnt into the board as one of the 7 options above.This is a very good board and remotes for the money paid.

Bought this after trying and failing to add crappy extra 433 mhz learning remotes to my existing door opener.I replaced the lot with this kit, using my existing 12v plug in power supply.Works great. Wiring - twin core cable to power supply, twin core cable to garage door opener and you're done.Easy to program the fobs (one press on circuit board, one press on fob), and the fobs are much nicer quality than the silver/black ones a lot of kits use.Four complete circuits, so if one button or relay fails you can just use another of the four. Good range too.Recommended - but DO NOTE you need a 12v power supply.

Works well but was supplied with 4 remotes but dont seem to be able to get more than one connected at once. No instructions on how to do it either

Was to be replacement controller for garage door,but very poor instructions as to how to install.

I used this to wire in to the push button on an existing garage door opener, having lost the remote and not being able to find a spare. The instructions are a bit weak, so you do need a bit of basic understanding of wiring, and the case isn't particularly robust, but the remotes are much better quality than I was expecting at this price.So in summary great value if you know what you are doing!

Used this for my gate, 2 garage doors and alarm activation, works really well, with a good range and very easy to program. Yes week impressed and very good for the money.

Does what it says

bought a slightly cheaper model from amazon but it suffered from a ghost signal and would open the garage door and gates anytime. fitted these and have had no problems of any sort since about 6 weeks. would recommend this . good instructions, works well, nice quality transmitters
