2.7.2 CONTACT CLOSURE INPUT LOADER

The Contact Closure Input (CCI0-17) Loader module generates a logic level (0/1) L-value output
for each connected CCI depending on an applied voltage or the contact condition of its associated
terminals (e.g., for CCIs 0 and 1, the minimum open or closed recognition time is 0.05 seconds; 1
V dc maximum = closed contact recognition level; 4 - 24 V dc = open contact recognition level.
See specifications in Section 1 of 53MC5000 Instruction Bulletin for CCIs 2 -17).

The table that follows lists the CCI0-17 invert parameters and outputs. An illustration of the
CCI module follows the table.
