Just an experiment so far, but because a single-channel prototype worked fine I thought I'd go the next step and build an 8-channel low-amp A/C ssr. This is a takeoff on Ernie Horning's use of the MOC3023 to control lights directly, eliminating the triacs completely since the MOC alone can apparently handle up to 1A. Obviously it's less expensive and quicker to build. Size: 3.75" x 2"
One sacrifice I had to make was running the A/C power trace beneath the optos. Hated to do that but realistically couldn't come up with another way to do it conveniently on a single-sided board. I reasoned that my plan is to use these with one string of LEDs per channel, so there won't be much current on the board at all and it'll probably work okay. Still, I hated to do it that way because it's a bad idea... I built one and if it tests out, I'll cover the hot traces with either liquid tape or hot glue for more safety and isolation from potential moisture.
I etched 3 boards -- the right two still have the toner on them while the left one is cleaned and ready to assemble. Also shown -- the completed prototype.
