QIACHIPDC 12V Relay Remote Switch Wireless RF Remote Control Switch 4 Channel Module 433Mhz Transmitter Receiver Kit Universal Remote Controller for Lights Fan Garage Door Opener Gate Car

This remote switch was easy to configure and works amazingly well. It can control 4 different circuits independently, and can be programmed as momentary, latching or toggle mode. All four switches must be configured the same type. Comes with two remotes with batteries already installed. The remotes feel good quality in your hand. You must pair the remote transmitters with the receiver on initial setup. It's not hard to do, but there are 0 instructions that come with the unit, however there is an instruction sheet for the item as one of the pictures on the Amazon sales page. In standby mode, it draws only 11.7 ma. I'm using this to control 4 different LED lighting zones on my truck camper. I have it wired up in conjunction with some panel switches, so I can bypass the remote controller and control the lights manually with the panel switches in the up position, or through the remote control in the down position. That way if the remote controller should fail or I don't have the remote with me, I still have manual control of the lights. Also, this allows me to eliminate the parasitic drain when not in use.So far, this little unit is performing as advertised, and I am very happy with it.

Found no problem with these, I have been using them for about 6 months now and have had no issue with them. Very good product. Fairly priced

Clearly, this is a bit of "you get what you pay for." It's not like this is a $100+ system...I'm using this to replace the keyless entry I built and installed in my 1995 Cherokee. The OEM keyless was IR, not RF and eventually died. I bought a different 4 channel remote and receiver about 10 years ago and installed to replae the OEM system. I've used is so much that the ABS buttons have actually been worn through.My one preference would be a way to flip which channels are toggle vs. momentary. Since the majority of my use would be one button to unlock and a second to lock, and I want to be able to toggle some lights, it'd be better if buttons A and B (the biggest) would be momentary, since they'll be the most used, and C and D would be set to toggle.As is, I'm a bit worried that it might be too easy to activate the lights when it's in my pocket, so I'll return to a vehicle with a dead battery.

CONSThe wire goes into a terminal block with the little screws and green sides ( this is in my RV ) i'm alway worried that the wires are going to short out with this style.takes a moment but you can find the information on the PCB basically its every third wire is input ( or ground depending on your set up ) on either side is NC/NOthe little plastic enclosure was worthless as i was not able to pack my wires in ( 12-16 ga wires ) i'm using 3 of the relays.PROit has an antenna that you can strech out / replace should you feel so inclined.The remotes are amazing. it says it can store up to 20 ( I was thinking of using the 433 mhz wall plates i'll let you know how it turn out ) range on the remotes is very good .Neutralno documentation was provided, if you do look around there is a picture that says hit the button 8 times to reset and 3 times to get the unit in toggle mode it is shipped in momintairy mode.you need to fiddle around to figure out which is A VS D block. a note on the PCB or yet documentation would have been nice.over all I really like it, if it brakes i'll provide an update. ( Id most likely just buy another to replace it )

so...I bought two of these. you can use the same remote to control both relay modules (just pair them at the same time).I use one at the shop to open, stop, and close the bay doors (set the momentary contacts in parallel with the up and down buttons and series with the stop) because the type of door opener does not allow for a typical garage door opener. but I still had one spare channel...so I wanted that to open the facility main gate. downside is that the main gate was about 200 meters away, so I put in the second module up there.these are great little rigs and one can control just about anything with them (maybe need some extra relays and stuff depending on what you wanna control).only downside is the remote range. maybe it would be stronger with better batteries, but you get a pretty crappy range of control maybe 20-40 feet. upside is that you can just extend the pickup antenna with a piece of insulated wire electrically connected to the coiled antenna wire inside the module. I ran it up the side of the shop so I can control the bay door from maybe 140 ft away.

The description leads you to believe that you can program the buttons however you like; not true. I needed 3 momentary buttons and 1 toggle, can't do this. The seller even responded to a question stating that button A can't be momentary with button B being toggle. I am using this to control power locks and it works great so far but that leaves two of the relays/buttons that I have no use for.

They advertise 50 mt range, tried it in a tennis court and the range is good enough from 8 to 10 meters.Will return it

Easy and straightforward to install. Circuit board is well designed with plenty of protection. Each relay is 100% independent of the others, allowing you to configure the 4 channels however you wish. Channels cannot be grouped (fire two relays with one button). Keyfob fits well in the hand and has a res light to confirm you are pressing a button. It's not too heavy and feels to be of good quality.Circuit board has good ripple rejection, and the signal is quite long range.

Nice size and form factor. Works as advertised. Nicer remotes than most. Programming was a bit confusing as instructions were typical off shore translation, but In the end function perfectly. Would buy again.

There are a ton of these products around but this one caught my eye because of the remotes. They look and feel almost like an OEM vehicle remote which was perfect for my application. Plus it comes with two!The buttons feel just like an OEM remote as well. However I'd like to note that if you're using this in momentary mode and have a need to hold it down for a long time then it does get somewhat tiring. The buttons are soft so it requires some force to hold it down. Not an issue if you're just pressing it once.MODES:Although you can mix modes, you can't specify which buttons each mode applies to. A+B are assigned one mode and C+D are assigned another. I would have liked the ability to choose, especially because the remote housing visually groups B+C together. Not a big deal though.COOL-DOWN PERIOD:This is not mentioned in the description as far as I can see but there is a cool-down period when using momentary mode. If you hold the button down the relay will automatically disengage after about 10 sec. Not ideal for me but I can understand why it's designed that way.Lastly, it comes pre-installed in a plastic case. This is actually a pretty big plus if you intend to use this as a standalone unit and want to mount it somewhere. In my case I didn't need it as I already had a project box for all of my various components.RF Range seems to be good. I have not tested it's limits since I am only using it in the vicinity of my vehicle. I have it inside of a plastic project box which is mounted inside of my truck bed so there are a few layers of sheet metal between the relay and remote. The signal drops on occasion but I can't tell if it's because of my finger getting tired from holding the button down.One feature I would've liked is the ability to program a single button to actuate 2 or more relays simultaneously. Probably not a common use-case but I ended up having to buy separate relays which are in-turn controlled by this wireless relay in order to accomplish what I wanted. Somewhat of a shame because all the hardware needed is already on this board.Overall this is a great device. I can't believe how affordable these things are nowadays.

Easy to program

Fast delivery

These kits can be used to enable remotes to control almost anything you can think of. Easy to program and wire up to operate mulit functions. The only thing I found anoying is the cut out for the wire to connect into are too small so I cut them out bigger to allow the wiring to fit into the appropriate slots on my apprication. I used them to upgrade my trave trailer awning to enable remote control from anywhere. These units can transmit 40 to 50 feet. Great buy for the money
