Thanks for sharing. I find it particularly interesting that you found SSRs that can directly switch the sprinkler solenoids. Many existing solutions use an optocoupler (triac output) plus a triac for each station, mainly because the optocoupler itself cannot switch high current. The SSRs you found have sufficient output current, and yet are pretty small.

We are currently away till Monday July 21. Orders placed during this time will be shipped on Tuesday July 22. Thank you for your understanding!
