Hi Keith

I'm only switching a max of 200mA @ 24VAC to operate irrigation solenoid
values. My homebrew controller can handle 32 valves (or pump controls) and
it all runs fine for the last 3-4 years apart from the occasional solenoid
going open circuit for no reason that I can find.

I'm looking for minor adjustments rather than wholesale redesign to save
money on solenoids!!
