    That looks good!

    I am little confused however as Jonathan has put that I require 24v..

    So would I run the 24v through the micros and then step down to 5v through the Optos?

    Also I'm looking to build a board that will max out the inputs to the PP..
    I have found a lot of them have drivers also/bi dir, but I am looking to DIY an input system that will handle as many inputs as physically possible.

    I have found this PP as a secondary, before I go ahead and but it, is this suitable?

    (Am I right in saying I am looking for an ECP/EPP compatible card?)
