QIACHIP DC 12V 1CH 433Mhz RF Wireless Relay Remote Control Light Momentary Switch Transmitter with Receiver (1 Relay)

Works exactly as advertised but be warned that there are several different remote control options and I did not get the one I was expecting (my fault, not theirs). There is the A/B remote, the single button remote, the A/B/C remote, and the brushed-metal A/B/(C/D?) remote. I thought I was getting A/B but I got the single button. Just review your selection more carefully than I did. Very easy to set up and wire. The instructions are quite good considering other similar products that may not come with instructions at all. I like that there's both an NO and an NC relay built into it for versatility.

Works great. The English User's Guide is attached.

I used this to make Halloween prop / animatronic remotes. It was so easy to wire a 12v power source, connect the wires, and power it up. The remote paired instantly and putting it in momentary mode was simple. This worked so well out of the box. Excellent value.

It is not clear that it is necessary to sync the remotes with the receiver before they will work. Other than that they work great.

I used this with a replacement horn on my car. I hooked it up about two years go. It has been very reliable with no problems. It can be activated from about 200 feet away.

One of my concerns was adequate range of the remote control so I preformed some measurements before I installed these in my Jeep to control the rock lights. As shipped the antenna is a short curled up black wire. Leaving the wire curled up and testing the range I found I could get 150 feet from the receiver and the hand held remote transmitter was able to connect and control 100% of the time. As I went beyond that point out to 175 and beyond the receiver was having difficulty seeing the click of the remote. It would work intermittently only. Uncurling the wire and making it stand upright I repeated the experiment and was able to get out to 225 feet before the receiver was no longer able to reliably respond to the remote. At 225 feet it was 100% reliable. Beyond that I could get it to work intermittently. Great features with their system able to interchange remotes from one relay or the other. The ability to program each button is brilliant and very flexible. I'll use a two button remote to control my system and a three button remote to program my strobes and then put it away until needed later. The remotes feel good in the hand, not cheap. Installation is simple with two wires for + and - 12 VDC and then the relay one input and the two outputs. One output is normally closed - it connects to the relay's common input when at rest and goes off/opens when the relay activates. The second output is normally open - it is disconnected from the relay's common input when at rest and comes one when the relay activates. I attempted to measure the current draw of the receiver deactivated and the current draw is so small my digital meter does read it - it's less than 0.01 amps. With the relay activated I read 0.025 amps or about 1/3 of a watt power so this thing is very frugal. I have no concerns about leaving this on my car battery for weeks and months at that low of a drain. There are no written instructions included so just print out the photo here or follow the video. I bought a total of five of these relays and will likely buy more. Good product.

Ordered 2, had to return one (for exchange) because the terminal block on it was defective, the tab inside the +V slot would not fully close and grip the wire. I was able to get the second one to work ok, only time will tell how long the terminal block lasts. The instructions are needlessly confusing. I simply wanted the momentary function. Ignore the instructions. All you do is press the learning button, the indicator led turns on red. Do NOT wait for it to go off as the instructions say. Instead simply press the remote button (while the indicator led is on). The indicator led flashes. That's all, you are good to go, the remote works to momentarily close the relay as long as you hold the remote button down. I could not figure out what step 3 meant, so I ignored it and simply repeated the above to pair the second remote. I did not try the other modes but it works as advertised for the momentary mode.

For years when adding lights on my truck it was always the same run wires, find a way to get through the firewall to the dash, drill a hole to mount a switch. These RF relays are great. I can operate lights using the provided FOB from inside my truck or outside the truck even when driving down the road. Run your pos/Neg up into the engine bay and wire to the relay. Program the relay and your done, no drilling or fishing wire through the firewall. Currently I have 2 relays installed one for LED's around the GMC logo on the Grille and one for a set of 7 inch LED driving lights.. I mounted a bus bar for positive and negative and connected the bus bars to my battery so I could have multiple 12V power sources off the Bus bar and multiple ground connections off the Negative bus Bar. I programmed the relays to open and stay open with 1 click and then turn off when clicked again. Comes with instructions pretty self explanatory if your familiar with 12V wiring. Run you hot wire to V+ and ground to V- . You also have to run a hot wire from your battery to the COM port. So your input to the relay will be 2 hot wires and 1 grouhd from your battery. Your output will use the NO port to lights etc...Make sure when coming out of the NO port you put an inline fuse to protect your device the relay is operating. Follow the included instructions to setup the relay the way you want to use it. Once you have power to the relay click the button on the Relay 8 times to clear any programming, the light on the PCB board will flash quickly then go off. for my installation constantly on or off I pressed the programming key twice, The LED on the relay circuit board will light up steady, press the key on the Fob you want to control the relay. your device should come on, press it again and the relay will open and your device will go off. So far pretty impressed for the price point.

Product is as described and works as expected. I have installed this wireless relay as a remote kill switch for the fuel pump relay on my car. This is now under the hood in the fuse box, and the remote control works fine from the driver seat.

Update: 11 February 2020 We have had some nasty cold weather here (-39C 60 km/hr winds = -60C wind chill) and the relay and remotes have been working flawlessly. Quite impressed with these relays and remotes. They seem to work quite well, have a decent range and can be configured for a wide variety of load voltages and have several modes of operation. If you want to use this relay in latching mode, you have to buy 2 relays to get the two button remotes (A - ON, B - OFF). The single button remotes only support momentary and toggle modes. The relay is rated at 7A max for up to 28VDC load or 12A max at 125VAC load. The relay does remember its programmed mode if it is disconnected from its 12VDC power source. The ones I ordered came with wiring and programming instructions that were easy to follow and understand. The remotes also came with 2 CR2016 batteries pre-installed in each. The relay output is isolated from the 12VDC required to operate the relay, so you can control just about anything up to 250VAC, as long as you do not exceed the relay current ratings. If working with non-resistive AC loads (such as incandescent bulbs, motors, heaters, etc.) you should probably de-rate by 10x to ensure you don't fry the relay with input surge currents when first turned on (i.e. keep your rated load below 150W at 125VAC). Remotes are sturdy, the buttons require a moderate press and have a tactile 'click' when activated.

Lo conecte a una cerradura electrica de manera normalmente abierto y funciona perfecto, ahora puedo abrir y cerrar una puerta de manera inalámbrica... muy recomendable facil de instalar y configurar con los controles.

product very nice and good quality , easy to install and configure

Die Einrichtung ist gut beschrieben und alles funktioniert einwandfrei. Man kann die Stromversorgung auch mittels Schalter unterbrechen, damit nicht ständig Spannung anliegt, und die gespeicherten Funktionen bleiben erhalten. Ich benutze die Schalter Kastenwagen um die Rückfahrkamera ohne Rücklichtschaltung zu nutzen und dazu extra Scheinwerfer einzuschalten.
