Number of Modules Per Series 90-30 PLC System
The following table lists the maximum number of each type of I/O and option modules that can be
installed in a Series 90-30 PLC system. The number of modules that can be installed in a system
depends on several factors, including available references for each CPU model, the current rating
for each module to be installed in the system, and other installed modules. Before installing
modules in a baseplate, verify that the total current rating of all of those modules does not exceed
the power rating of the power supply.
