Use I/O Modules with CompactLogix 5370 L2 Controllers Chapter 8
Embedded Digital I/O Points
The embedded digital I/O module on CompactLogix 5370 L2 contains sixteen
24V DC sinking inputs and sixteen 24V DC sourcing outputs. The inputs can be
configured to use digital filtering by input group. Filter times can be specified for
OFF to ON and ON to OFF.
Group 0 is used to configure inputs 0…7. Group 1 is used to configure inputs
8…15. The default filter time for each group is 8 ms. You can the filter times to
0.0 ms, 0.1 ms, 0.5 ms, 1.0 ms, 2.0 ms, and 4.0 ms, as shown in this graphic.
