12V RF Wireless Remote Control Switch 10A Universal 4-Channel 433MHz Remote Relay Switch for LED Lamp, Lights, Motor, DIY Function & More (4 Transmitters with 1 Receiver)

All 4 channels worked fine in momentary mode. Haven't tested range or other modes yet. I'm running a small 12v geared motor forward and reverse using two relay channels. Motor wired to relay armatures. Relay no both wired to +12v, nc wired to -12v. Chan1 is forward, channel 2 reverse. Haven't tried reprogramming.I used with geared motor and simple "flapper" to remotely close and open the entrance to my bluebird house to discourage undesirables like sparrows.

I used it to control screw motor to raise and lower bed in our RV.I had a switch but the location was difficult to reach. replace DPDT toggle with this and am very happy.

Very handy and easy to hook up

This is a very good device, but the documentation is poor.The remote buttons are labeled A, B, C, D, but the terminals for the four relays on the receiver module (one for each button) are labeled 1, 2, 3, 4. On the unit I received, button A control relay 4, B controls 3, C controls 2 and D controls 1.I've seen some questions about the amount of load current that each relay can control. Rather than just considering the relay contacts rating, pay attention to the unit specifications and the size of the terminal block and printed circuit board traces. The specifications on the unit I received state "Output current: less than 3 Amps" and "Max load current: 20 Amps". I'm not sure exactly what that means. My guess is that each relay and the associated terminal block can handle something less than 3 amps continuously, and maybe 20 amps momentary -- but there's just no way to know.

I use this to control a rotating transducer pole for my fish finder on my boat, works perfectly very happy with it so I ordered another one to build one for a friend.

I have a Lobster tennis ball machine. Lobster charges $169 for the remote kit that connects to the circuit board--it says Lobster on the transmitter. This remote kit cost $14.99 plus tax and doesn't say Lobster on the transmitter. It also worked 80' away. Not a bad tradeoff.Easy for me to install, once I thought about it awhile.Step 1: figure out where in the machine to run wires to get power for the receiver itselfStep 2 find the wires feeding the motors I wanted to control, cut one and connect the ends to the remote.Step 3: Set the jumper on the receiver for the function desired (toggle)Step 4: test machine.Step 5: Go hit balls and confirm satisfactory range.Step 5: write a blog post.Step 6: write a positive review.

They work perfectly for my purposes with a range of at least 60 feet. Bought two and they do not cross operate. Nice compact transceiver set with relay outputs which can be used for any number of switching processes.

Great product for the job at hand. Fantastic value, all.4 channels worked perfectly.
