Power and Expansion Selection  
This section provides tools to calculate the CJ1 system current consumption total needed to select  
the power supply. When the number of modules or power requirements exceeds the capability of the  
power supplies available, I/O expansion racks solve the problem. If the number of modules per rack  
exceeds 10 or the current consumption is greater than the capacity of the power supply units, use the  
CPU and expansion rack configuration.  
What is the basic configuration?  
A CJ1 system consists of a power supply, a CPU, and up to 10 basic I/O, special I/O and  
CPU bus units, and an end cover. See page B-109.  
What goes on expansion I/O racks?  
The expansion I/O rack contains a power supply, an I/O interface module and the remaining  
I/O modules. Each expansion rack requires a power supply, the I/O interface module and up  
to 10 more modules.  
Where are ratings to calculate overall current consumption?  
All the current consumption ratings for the CPU, basic I/O, special I/O and CPU bus units  
are collected in the tables on pages B-110 to B-111.  
Which power supply is right?  
Compare the current consumption total of basic I/O, special I/O, and CPU bus units to  
determine which power supply to use.

Note: If more than 10 modules are required or the current consumption exceeds the output  
capacity of the power supplies, go to page B-109 for configuration of I/O expansion racks.  
The same power supply units can be used for both CPU and I/O expansion racks.  
How many expansion I/O racks can be used?  
Depending on the CPU chosen, the system can be expanded with up to three additional racks of  
basic I/O, special I/O and CPU bus units.

Note: Order one CJ1W-IC101 I/O control module for the CPU rack and one CJ1W-II101 I/O  
interface module for each I/O expansion rack. Connect the modules with a cable of  
the appropriate length. Second and third I/O expansion racks connect between I/O  
interface modules. See page B-117 for details.
