Publication 1771ĆIN034B-EN-P - August 2002
I/O Module Groups
Each module condenses 2 full module groups (32 outputs) into each
I/O chassis slot. For example:
Module group 1 = outputs 00 through 17
Module group 2 = outputs 00 through 17 (module group 2
represents the second set of outputs).
Terminals 1 through 20 represent module group 1. Terminals 21
through 40 represent module group 2. Terminals 10, 20, 30 and 40
are DC common and terminals 1, 11, 21 and 31 are DC power.
