Will this do the trick, based on my schematic in my other post? Or is there a better unit I should be lookng at? (The photo says 12V, but the description is for the 120V model.)
Also, I'm looking at the 7 line model, which you have to use the pull-down to see the specs on. (This will only link to the 4-line page.)
