Sorry for this very naive question.
I'm not supposed to post this, but the AB tech team here in my area are out of reach.
I will be using 1766-L32BWA, on the catalog it says, 12 digital fast input, 8 digital normal input & 12 relay output.
What does the fast & normal means? Why are there more fast than normal input?
