I have a pressure system with eight solenoid valves on it and I'm controlling it from an Arduino. For each valve I have a solid state relay that an Arduino controls to switch on and off 12V from the supply. I've gotten this circuit to work properly with a single relay and solenoid:
Now I'm beginning to scale it and it all works but my setup is pretty messy. Here is a single SSR hooked up to a single valve and then the holders for all the other SSRs on the board:
So I was planning on using that terminal connector and then that small proto board mostly because this will be changing around a lot and I may be throwing some more pieces in so I don't want it to be 100% permanent but I do want it to be more durable and a little more elegant. Any thoughts on how I should wire this up? Or anything better than that terminal connector?
Here is a schematic of half of the full setup:
