Instead of spending $1,000 on a dual swing automatic gate opener I have found some $45 linear actuators that should do the trick If I can figure out how to apply the correct voltage to them through my Elk.
The actuators extend when +12v is applied and retracts when -12v is applied.
I have an M1 and a M1XOVR and some Elk-912B relays im not using.
Does anyone have any clue how I can have the Elk apply -12v for close and +12v for open. I assume I will need some sort of relay circuit and I would imagine there is a name for the type of relay I am looking for. I just dont know what to search for.
