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

Works great for my campervan eliminates a lot of switches and wiring.

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.

Here is what I found:The 6-button Remote Control is pre-dedicated to the relay board. Other remote controls (Fobs) cannot be programmed to make this relay board work. Button 1 on the Remote Control works Relay 1 on the circuit board, etc.Clear Control Code: The Control Code determines whether relays are momentary (turn on with button push on the Remote Control and turn off when that button is release), toggle (turn on steadily with first push, off with the second push), or "Interlock." Whether it's the initial programming of this code, changing the code, or repairing a goof, do it by pressing and holding down the tiny white Learning button in the corner of the circuit board, holding until the red LED lamp at the switch base goes completely out.Enter a new Control Code: Press and release the Learning button once. While the LED lamp is on, chose your desired code from the 6 options listed - before the LED goes out.Some other stuff:A plastic box/housing came with the unit from this vendor. The housing, pictured, provides access to the relay wiring terminals and leaves each LED lamp visible that stays on for each relay that is activated.There is room between. the backside of the circuit board and the bottom of the box for one layer of additional backplane wiring. This wiring cannot go to the edge of the board where it would interfere with the cover's seating.The only output power available at the relay terminals is that which is wired into the SPDT terminals.

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.

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.

The media could not be loaded. Adjunto video de evidencia, al pulsar las opciones la #2 no manda señal a la tarjeta.

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
