OpenSprinkler Forums Hardware Questions 12-Volt DC Solenoid Valve Supoprt Re: Re: 12-Volt DC Solenoid Valve Supoprt



Hi Ray, thanks for your reply.

I have seen that blog post, would I be correct in saying that I need to…
# replace the following triacs×168.jpg with a 2N3904 transistor
# swap my 24v AC to a 12v DC power supply

Last few questions…
# I only plan to power one solenoid, would I need to replace all triacs?
# The Pi will be happy with this setup?

Thanks for your help again, the world of triacs and transistors are very new to me 😉
