Hello,
I've been learning from the archives, but haven't seen my particular situation addressed.
Question: anyone make 12vdc solenoids for sprinkler valves anymore?
Backstory: I want to control a drip line irrigation setup (2 or 3 zones) to water a veggie garden and there is no AC power available. I've a solar powered fence charger that uses a 12v battery that would be fine. I also have an older Rainbird ISA-408 controller which uses a 12vdc wall wart and obviously uses 12vdc to control the valves (solenoids).
I'm having trouble locating 12vdc solenoids since 24vac seems to be the norm, so experimentation indicates the ISA-408 will trip a modern valve, but it latches for some reason and stays open when it should've closed. If I disconnect the wire, the output from the controller goes to zero, like it's supposed to.
I've seen battery powered timers that attach to a hose bib, but they control one zone only and are usually low flow, like 5 gpm.
It'd be nice to use a modern 24vac timer but that's a long (200') extension cord or a control wire. Burying cable probably isn't feasible either since the field is likely to be tilled once or twice a year for a few years.
Cheers,
