You can place your input module in any I/O module slot of the I/O chassis. You
can put:
two input modules in the same module group
an input and an output module in the same module group.
Do not put the module in the same module group as a discrete high density
module unless you are using 1 or 1/2 slot addressing. Avoid placing this module
close to AC modules or high voltage DC modules.
