I've replaced the attachment with a clearer one....
I've been working on my control panels for weeks. A new job position has cut into layout time, but it was never to be a race for me :-). I have the panel surfaces made and have all the components shown in the diagram. I started to wire it up, but want to pause and get a sanity check. I'm enjoying learning about electronics but I make no claims of competency. Here is a planned wiring diagram I created in Sketchup. Of course it is not schematic syntax accurate, but makes enough sense to me. My layout will have three control panels, a primary and two secondary. There are four basic circuits. Primary panel to power block, primary panel to tortoise, primary panel to secondary panel to tortoise, primary panel to secondary panel to power block. Every block and tortoise will have a toggle and led indicator on the primary panel. Some will also have a second toggle and led on a secondary panel. For dual panel items I want a toggle change on either panel to be correctly indicated on both panels. All told, the primary panel has 26 tortoise circuits wired in parallel on 12VDC 2A wall wart and 20 power block relay circuits wired in parallel on 5VDC 2A wall wart. I won't be too surprised the if electronics gurus find all kinds of wrong here. Hopefully i'm not too far off.
My main questions are...
Would it be any better to use the 12V supply for everything, using resistors to make 5V for each power block relay circuit?
What can/should I do to protect this design from some stray current anomaly ruining the whole thing?
Thanks everyone.
