By small, I mean I'm trying to get 2 relays and timing control on a circuit board that is 1 and 1/2 by 3/4 inches and it's already obvious It's gonna be a tight fit. I could jump up in size on the board but it kind of defeats some of what I'm trying to do, so for now I'm trying to make it fit.
Yes the coil is 24vac. I can change that, but again for space considerations I was trying to keep everything common.
How small is the smallest 12v regulator (that has a reasonable price)?
Also, I assume that a 555 could be set up to a 40 sec. +/- 5 delay without too much additional equipment. From what I've seen it looks like I would need a couple of resistors. does that sound about right? Or am I missing something important?
Oh, and thanks again for the help. Even the questions are opening up eyes to other possibilities.
