DieseRC DC 12V 24V 30V Secure Remote Control Switch Universal Wireless 433Mhz Rf 10A Relay Receiver Board with 2 Transmitter Key Fobs for Motor Light Gate Door DIY Wireless Controller

Bought an old house and needed a set of clickers for the garage doors. The old ones were lost by the previous owners. The openers still had push buttons on the wall but no remotes so I took a chance on this device. Turns out that it works great. The radio needs an external DC power supply between 6 and 30vdc. I used an old 12vdc power brick from an old laptop, just cut the end off and spliced the wires into the supply terminal (the one with the 3 screws). Programing is a bit tricky, as others have stated, you need to do it quickly, so familiarize yourself with it first. Button A controls relay#1 .. button B controls relay #2, you only need to program the remote once as a single programming session handles both relays. In fact I programmed the remotes on a bench before installing them on the ceiling. I programmed the device for a momentary connection (since the garage door buttons are like touching two wires together). You'll hear the relays when they click in (ie. pressing the A button) and when they click out (ie. releasing the A button). I used the NO (normally open) and COM (common-ground) connections on the relays for this.

I used this on my open closed sign. Worked great.

1st of all you have to set the remote/s to Momentary Mode.1. Confirm that both red LEDs on the circuit board are ON.Which means the 2 DC power wires are connected correctly i.e. the 2 left connectors on the 3 connector panel & it matters which one is left and right so if no lights, then reverse the wires.2. Press the learning button on the receiver 1 time.3. Watch for the indicator LED on the receiver to turn OFF.4. Immediately press the button "A" on the remote transmitter.5. Watch for the LED to start flashing then stay OFF.6. Immediately press the button "B" on the remote transmitter.7. Watch for the LED to start flashing then stay ON.8. Congratulations, you have programmed Momentary Mode.It goes quick so if you missed it try again.NEXT connect the top Normally Open wire & the 2nd COM wire to your garage door opener wires. Ignore all the other connections. If it doesn't work, reverse the wires.

This is a very well-designed receiver and remote control with a good range. It is a bonus that this comes with 2 remotes.Time is of the essence when programming. You must start over if you take too much time between the steps to program an Operating Mode. So I would have written the "How to Program" like this for Momentary Mode, but the same timeliness applies to programming the other modes:1. Confirm that both red LEDs on the circuit board are ON.2. Press the learning button on the receiver 1 time.3. Watch for the indicator LED on the receiver to turn OFF.4. Immediately press the button "A" on the remote transmitter.5. Watch for the LED to start flashing then stay OFF.6. Immediately press the button "B" on the remote transmitter.7. Watch for the LED to start flashing then stay ON.8. Congratulations, you have programmed Momentary Mode.IMPORTANT: Repeat the same steps for the 2nd Remote. I programmed one remote for Momentary Mode. When I tried the other remote, it was still programmed for toggle mode from the factory. The fix was to simply repeat the 8 steps above with the 2nd remote and now both execute Momentary mode.I did not see the type of battery used in the remote listed anywhere, so I opened one of my remotes so you don't have to. The remotes use a slide-in CR 2016 battery.I am using a 12 VDC power supply which is 16 VDC with no load and about 14 VDC powering just the receiver. I use an external relay, a diode, and the normally open contacts of each relay to run a DC motor clockwise and counterclockwise to open and close Levolor blinds.Hope this helps.

I usethem for remote door releases. I have bought and installed both the DC and AC versions and for over a year none have failed under near constant use. my customers love the convience and price point these come in at. great fro a remote light switch etc.

I built a remote start for my old Jeep using this, and it's mounted behind a steel dash in a double wall fiberglass body. I can start it from inside my house from a good distance.Update....Only worked a week. Now I hear a faint ticking when it is powered up and LEDs are lit, but nothing happens. It performed well for that week, but only a week isn't a very long life.Update 2.Make sure you have solid power and ground. My power had come loose, causing low voltage under load. I'm leaving this all here hoping it may help someone diagnose.

Light weight. Basically wire size 18 awg or less. Needed two separate circuits so chose this unit. Was able to accommodate the light wire. Worked great at first, decent range on the remote. Unfortunately lasted only about 3 weeks. Then failed. The power indicator light (which shows when powered up, in my case with a 12v. battery) no longer lights, and of course the switch no longer operates. Disappointing. Cannot recommend.

I needed to control a motor remotely. This was easy to wire and works as I hoped.
