I would appreciate any help or direction. I have been working on a project for the last few months but while I'm pretty handy, the last time I did any real electronic work was putting together a HeathKit in Jr High shop class (1974 or so).
My problem is that I'm trying to put together a physically small delay to work on a 24VAC circuit. At this point I don't think it needs to be that precise +/- 5 seconds would be fine, and I'm thinking 40 seconds delay is what I need although that might change to as low as 30 or as much as 60.
Upon power up I need the delay, then for power to flow to the coil of a 24Vac relay. Once on it needs to remain on until system power down.
I've looked at 555 timers but I'm trying to keep the size at a minimum so I don't want to use a transformer unless that is the best way to make it small.
Thanks in advance.
