Wiring Dia. using SPDT relays to operate Pop door

I hate to post a link to another site but......

I have built this opener using a dpdt relay instead of 2 spst and it works. I currently use a 12v home security system battery lasts quite a while, recently I installed a trickle charger to the battery (nice if you have power); battery has lasted a year so far.

Do you know how to hook up a solar switch to this circuit? I built this opener, it works but I want it to close at night and open in the AM.

working on replicating your wiring diagram for a coop door. Two questions from a novice tech......is that a ground in the middle between relays and if so what does it ground to? Secondly, assume the 12v in at fuse is the power red and then the two wires left for switch (timer) are the neg leads to complete circuit? hope those ? make sense.....always had a wiring mental block. I keep blowing fuses and have checked and re checked wiring which appears to be right, only leaves a grounding problem or incorrect power hook up I think. Appreciate a little help. just want to make motor work on table at this point!! if I just hooked up a 12v power supply without a switch (timer) how would I do that correctly and what about those center grounds between relays?

Thank you for your info on your auto chicken door.
I had to replace a window motor in my car, the motor still works great it was the cable that was bad, so I want to use the motor for my chicken coop. I think your info will help me out.

Thanks again for it.

A DPDT relay can do the job with a simpler wiring layout.

Here is a simple wiring diagram I found that will work with 12v dc motor using 2 limit switches , 2 diodes ( 1N4001) from Radio Shack and 2 automotive SPDT relays. This is a easy set up for making a auto chicken coop door. I am using a car window motor. I hope this helps somebody out. I couldn't seem to get any help from anybody about it. Where it says Norm Open on the right side is where you would use a 12v Timer

Ok so this thread is very old (Like you said tho "I hope this helps somebody out. I couldn't seem to get any help from anybody about it.") but I just want to point out two things.

First thing you don't need the diodes if you wire it like this.

Two options.

Option One:
Using this harness will make this so much easier.
Harness linked in video description..
I did not install Limit switches in the actual setup but follow the diagram and it works.

Option Two & Second thing:
Second thing. Using the right timers.
Different setup using just two timers and no external relays but still using limit switches.

Upon further investigation of your circuit I came to the conclusion that this would NOT be a good one to use for a chicken door.

1. This is a single push button latching circuit. Press it once and it goes in on direction then stops, press it again it goes in the opposite direction then stops. That is good if this was to be manual operation, and even then it might not be. (More on that later.) Well the problem is that the timer will not know in what direction it needs to go. If there is a power failure, all the timer knows is to turn on. So if the power fails during the time it opens in the morning, it will not open the door, but if the power is restored before night fall, the timer turns on for closing the door, but all it does is open it. Leaving the door wide open for predators.

2. Running this in manual also has problems. There is no stopping the door midway. If for some reason it does stop midway, you won't be able to turn on the timer or press the button to get it moving again.

Yeah looks like if door is in between, for whatever reason, then it won't work. Just curious. Not gonna use this for auto door, but was wondering how to fix, to use elsewhere.

Yeah I made the diagrams just in case anyone needed the but the clap OP has not been on since the last time they commented here. So never posted. I'll did them up. And PM to you.

No it can't. The relays latching and alternating. You can get get a DPDT to latch but not in two seperate direction off a single button.
