I hope you understand this diagram. I'm not the best at these things. I tried to draw it as simple as possible. You could use terminal blocks to organize the wires better. I use wire duct to hide all the wiring. I don't like any visible wires. Din rails and/or backplate for your enclosure to mount on. I would also add a switch to manually stop each motor so u can manually open one set a time.
On the dpdt relay
Terminal 4 and 5 are jumpered together with a short piece of wire.
Terminal 8 and 1 are jumpered together.
This is how polarity is reversed. 1 and 4 normally have power. When the relay is triggered by the timer it switches to 5 and 8. When you reverse the - and + on a dc motor, it changes direction.
Terminal 12 and 9 are the power in on the relay and always have power.
Terminal 14 and 13 are the trigger. 13 always has - power. When the timer turns on, it sends + power to terminal 14 and it energizes the coil.
The diagram is for any standard 8 pin dpdt "icecube" relay rated for over 15 amps.
Any 24v timer
And a 24v power supply greater then 10 amps.
