433mhz 12V 24V DC 6 Channel Wireless Remote Control Relay Switch 24V/12V Remote Relay ON Off Transmitter and Receiver Universal Motor Light Door Window Controller (12V-24V 2X Control 433MHz)

This device actually works, very pleased with the outcome. I built a remote trailer brake and light tester, this device made the build super easy.

IT WAS PERFECT FOR WHAT i NEEDED. THE DOCUMENTATION WAS LACKING AND THE MARKINGS IN ENGLISH WERE ONLY ON THE BOARD AND WERE EXTREMELY SMALL. YOU MIGHT INCLUDE A DOCUMENT THAT SHOWS THE OUTPUTS.

The clear control code information.....hold the button, it flashes, wait....it flashes again then goes out again....NOW the code is cleared. Now you can re-learn the transmitter/s.I use mine in a custom RC semi-truck to control led's, some 12vdc(most of them) and some 5vdc. I didnt want pass through voltage....Im happy it doesnt. I have another unit that does and it works for that purpose.ALL 6 RELAYS do work at the same time....again, thats what I wanted.All relays are set to latch on button push....one relay will control a simulated horn, which is easy enough to quickly turn on and off or.....let it rip!This unit will ultimately control 64 plus led's and other devices.

Using and setting up this system was easy. The problem is with one of the remotes. 1 works great but the other works as a momentary switch. You push the button and it turns on, you take your thumb off the button and it turns off. This is not good.

Worked well - only issue was couldn’t use more then one relay at a time even with the two remotes - so if one relay was active with one remote you couldn’t activate a different relay with the other remote - next year I’ll look at getting single board relay’s so we’ll have more control over the Halloween props. Anyways it was better than the hard wired buttons I used in the past.

I spent a "HUGE" Amount of Time Learning, Testing and Documenting Clear "Setup" Instructions. Finally, I figured it all out and so it was Time to Use the Device. 1st... It has "Issues" regarding Setting "Each Relay". Not Possible.So I "always" use 12vdc "Individual" Relays for all my 12vdc Devices - for Multiple Reasons. Have for Many Years and have "Never" been Disappointed. They Require a Miniscule Amount of Amperage to "Engage", so I let the "Multi-Relay" (ie. like this one) Engage the "Individual" Relay and then I Let the "Individual" Relay run the Actual Device. Works Reliably 1st Time - Every Time.But when I Connected this Relay Device to my 1st Individual Relay and Initiated the Power from this Device - my "Individual" Relay would not Engage. So I Tested Multiple Button/Relays. Could not get Any of them to Initiate my Individual Relay. Even Tested the Relay (was Good) - as well as - tried other Individual Relays - with the Same Results.So... I took out my Ohmmeter to see if I could Figure out "why". Turns out... Yes... The Input Voltage "is" 12vdc, but the "Output Voltage" is in mA (MilliAmps). It "does NOT" transfer the 12vdc Input to the Outputs. Caught me by Surprise as I've Never Experienced a Relay (and I've Used a Myriad of Different Ones over the Years) that did not Transfer the Input Voltage to the Output. This is a Big Deal.Bottom Line (for me)... Worthless/Useless. Sent it back.

Did all it said except it lacks range. Will not do 40’ even in line of sight, outdoors.Instructions are almost non existent. A few poor quality pictures and almost no words.

i thought i was sent a defective unit. it was my error. they sent a replacement and helped me immediately. it was my fault. the unit works greati have tested it to about 100 yards and it works at that distance.the smaller units without the remote with antenae only work at about 20 yards max
