Irrigation Controller Wiring.

Worth1 · April 21, 2013

For those of you that are interested here is what I have been up to.

Many people dont even think about what something looks like they just want it to work.

I spent yesterday drilling a 2 1/2 inch hole through my wall to put all of this up.
The conduit was bent with a heat gun.

After that I sat in a chair and ran and connected all of this wire you see.
Including all of the fork connectors.

I got rid of the 2 24 volt AC 1.250 amp transformers that came with the controllers that plugged into the wall and installed these in their place.
They are 24 or 12 volt AC 2 amp transformers.
They are the 2 metal things on the bottom left.

The reason for this is to have power for other time delay relays or what have you.
Besides the factory ones were ugly and took up space at the wall outlet.
I couldn't even plug two in same area.
This solved that problem.

The Back flow prevention will be right outside the wall.
I can now tap into the 120 VAC for heat trace to protect it from freezing.

The reason for the terminal blocks is so I can map out the sprinkler valve wiring with jumpers.
The little box in the middle is a wireless radio controlled receiver for the rain/freeze sensor out by the road.
This is NOT your average irrigation setup by any stretch of the imagination.

I built the entire thing myself and connected it to the two controllers.

The outside J Box will be where all of the conduit will connect from my control valves.
I dont want to direct bury the wire. this way I will never have a problem with it.
This is taking some time but I am getting there.

Coming from an electronic background, I can appreciate the attention to detail. The flow of wiring looks good. Did you fuse the xformers?

Thank you.

Not yet I have some Weidmuller fused terminal blocks stashed somewhere.
They are old style and I dont know if I have the track for them.

They will get fused though.

It would be a shame to put an ugly inline hobby fuse in the box.

It is really hard to find things around here.
I went to several electrical supply places and finally found the terminal blocks at Fry's

Sometimes I miss working on the coast with so much heavy industry.

If you noticed the wires are not labeled.

All you have to do is count down and you know what everything is.
I do have numbers I will put on later and a set of prints I made up that will go in the J Box.
