Abstract
The present invention is drawn to an I/O block (38) assembly comprises a plurality of specifically configured I/O blocks (38) mounted to a conductive column (46) providing power to and communication between the I/O blocks (38) with each individual I/O block (38) programed for a specific function requiring that the proper I/O module (42) must always be inserted into the right base (40). This is accomplished by providing a set of pegs or pins (50) individually configured on the base (40) which match a complimentary series of openings 74 on the I/O module (42) formed by a mask (70) covering a plurality of holes (60) while leaving the holes matching the pins (50) uncovered.
