I own one of these.

But you will need 5v outputs from something else to control it (logic level ttl is all the juice you need, which is why I bought it, I use it to convert the CAI webcontrol outputs to full size relay closures).
It looks to me like you are trying to control Elk zone status using a computer? You would need a way to output 5v from your computer to control this relay board.
I think the gizmo you have already will work just fine. I think the doucmentation lacks. Just take an ohm meter and test the screw terminals see which ones are closed to ground. The turn them an on and see what closes to ground then. Then wire it accordingly. Elk zones are not going to be bothered by any slight noise or electrical "leak", especially if the only thing you have connected to it is your Elk and you use the Elk's 12v aux power to power the unit (check your total Elk amps if you do this)
