    Hey there,

    I have simple question. I think it was already answered in the forum, but I am bit confused with the answers for olded devices etc.

    For example here:

    Announcing the First DC Powered OpenSprinkler (v2.3 DC)

    There is said:

    What’s the operating voltage range for v2.3 DC?
    Although v2.3 DC comes with a 9V DC power adapter, you can power it with any voltage ranging from 5~24V DC.

    But I have 3.0 with 7.5VDC adapter.

    Can I connect 24VDC valve to OpenSprinkler 3.0 DC version?
    Do I need use 24VDC power supply?
    If I try to use original adapter 7.5VDC and it will not be enough, can it cause damage in electronic?

    Use the supplied adapter!

    DO NOT connect 24V to your DC Opensprinkler.

    You can use 24VAC solenoid valves with your DC OpenSprinkler. I don’t think I’ve seen 24VDC solenoid valves around.



    24VDC is industry standard. Every factory has 24VDC valves.
    It would be good to edit link above where is said that 24VDC is ok.

    Can I use a relay betwen opensprinkler and valve? I have 5VDC relay for arduino could be work?
