I'm scowering the interwebs looking for a 5v signal 12v operating stdp relay board for running 12v ballvalves off a 5v signal. operating amps of the ball valve is 1.2mA. I'm still learning, so i'm sticking with prebuilt boards, as i'm learning more coding than electronics theory right now. Any help on locating something like this would be greatly appreciated.
Thanks
Have a look a this. I run it directly from an UNO.
if you linked or attached something, it didn't come through
Fast and incomplete reply from me. Again...
disconnecting the jumper from JDvcc to vcc and connecting the 12v power and ground to the 3 pin jumpers?
No. I bought the 5 volt version of the relay. That means that the coil in the relay runs from 5 volt. As I use USB power I feed the relay from the 5 volt pin on the UNO. The signal for activating the relay connects directly to the UNO.
I did measure the current consumtion of the coil and it's very low. If You want I can measure again and tell You.

That doesn't sound right. Are you sure it's not 1.2A?
Single Throw Double Pole? Never seen that on a module. Wiring diagram?
If you want to stick with pre-built boards, get a dual relay board and control both relays from the same Arduino pin.
Pay attention to what you buy; opto-isolated and with a JD-Vcc jumper.
