I/O Module Groups
Each module condenses 2 full module groups (32 inputs) into each
I/O chassis slot. For example:
–
Module group 1 = inputs 00 through 17
–
Module group 2 = inputs 00 through 17 (module group 2
represents the second set of inputs).
Terminals 1 through 20 represent module group 1, with terminals 9,
10, 19 and 20 ac low (L2). Terminals 21 through 40 represent
module group 2, with terminals 29, 30, 39 and 40 ac low (L2).

Terminals 1 through 20 represent module group
1,with terminals 9, 10, 19 and20 ac low (L2).
Terminals 21 through 40 represent module group
2, with terminals 29, 30, 39 and40 ac low (L2).
Module group 1 = inputs 00 through 17
Module group 2 = inputs 00 through 17 (module
group 2 represents the secondset of inputs.)
If multiple power supplies are used, do not exceed the specified isolation voltage.
