4 Channel SSROZ Assembly Instructions

Background

I was a late starter to the CC.com website last year and missed out on Sean Bowf's COOP for SSRs and decided that I would go ahead and make some of my own. This SSR design is a result of collaboration with Sean in January and February 2007, making sure that this design follows the guidance for SSRs as published on www.simpleIO.com and my calculations and testing.

The SSROZ design is currently in it's 4th iteration.
