Digital Inputs
Four off-the-shelf versions of the MC4000 are available.
These are the , ,
and . Each version has
four standard 60-pin IDC connectors. Each connector is
logically separated into two 30-pin groups, with each
group supporting one motion axis (except for the PRO
and STEP versions that have two axes per group for a total
of 8 axes).
