Hi all
99% of the PLCs I have seen have used 16 point input or output digital cards, in some cases many slots such as 8 cards to make up 128 inputs. Why not use high density IO 32 point cards so only four slots are taken up? Is there a sound engineering reason behind this?
I am looking after a vendor installing our first Control Logix on site and they have selected to use 32 point cards and Im happy to do so.
