So I have this project where I am using an Arduino to control our in ground Sprinkler Valves.
The specification on the product page says Max 70W DC or 35V AC. Sprinkler valves run 24VAC, so I thought this should be a slam dunk.
(ref: seeedstudio.com/depot/relay- … th=132_134)
The specification on the wiki page, which I seen after I purchased the product says:
The max switching power is 35VDC 70W for each channel. It can be directly controlled by Arduino/Seeeduino through digital IOs with external 9V DC supply.
First question, can this be used to control 24V AC Sprinkler valves?
So I have it all wired up, except for the power supply. The power supply I have says 24VAC 14.4VA. It has two wires, that both have a U on that hooks to a screw. (This was to the old sprinkler control.) In the book for the old control, they are hooked to the screws that say “AC”, and doesn’t say if the one with the white strip should go on one side or the other.
The Seeed Relay board has screws for 9V and GND.
Am I missing something here?
