EM, NEMA, whatever - if it controls a traffic signal, you can talk about it here.

V2 Update!

This version utilizes solid state relays and supports 2 signal phases as well as a ped phase. The ped phase can be recoded/rewired to be a YAGA addon, but I'm getting a ped from Mike soon so it's being saved for that. The solid state relays are much better!

cool beans! Question, is that ground bar being used as a 120v buss? If so, cover that baby for protection!

Also, add a fuse in there, trust me, your SSR's will thank you!

Yeah it is, before the bar I was using pigtails and wire nuts and it was a horrible mess. I readded the warning label and I'll cover it with electrical tape after making sure all of the connections are tight.

Good idea, I have a spare sitting around, could easily throw it in.
