I have this SSR and am wondering how it could be used in Arduino. It states 3 to 32vdc input and the output is 120vac.
I have applied 18vdc to the input but the output stays open.
Is this the wrong approach?
Are you controlling AC or DC? AC relays are made with TRIACs and a TRIAC doesn't shut-off 'till the current drops to zero. With AC that's the next zero crossing (twice per cycle). With DC, it won't shut-off 'till power is removed.
Controlling DC. I'm assuming I will need to input ac for it to work. It will not switch DC current?

Don't be ridiculous!
If you need to use a SSR to switch DC, then you need to get one designed to do that.
Exactly what are you trying to do?

You need to put a load on the SSR in order for it to turn on. You can’t bench test an ssr with an ohm meter...
That ssr uses dc logic to control an 120v AC load.
Ok I see. So I will test it out tomorrow on a pump and see if it works. Thanks.
Don't forget the series resistor to protect the output of the Arduino and input of the relay.
Hmmm. From what I am reading on the data sheet, I will not be able to use this on a DC circuit. Easier to just buy relays made for Arduino.
or get a dc ssr....
