CJ1 SYSTEM POWER AND EXPANSION
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.
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 is the basic configuration?
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.
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.
What goes on expansion I/O racks?
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.
Where are ratings to calculate overall current consumption?
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.
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.

JBasic Configuration
A CJ1 Series basic configuration consists of a CPU, Power Supply Unit, Basic I/O Modules, Special I/O Modules, CPU
Bus Modules, and an End Cover. Add up the current consumption of all the modules and the CPU according to the
formula on the following page and then select the Power Supply Unit right for the application.

JCPU and Expansion Racks
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. This divides the load from the modules across two Power Supply
Units. To ensure communication and automatic channel assignment in programming, order an I/O Control Module for the
CPU Rack and an I/O Interface Module on each Expansion Rack.

JCalculating Maximum Current Consumption
A. Calculate Maximum Current Supply (See the table below.)
•Current required at 5 VDC by all Modules in column (A) ≤Maximum current consumption shown in table
•Current required at 24 VDC by all Modules in column (B) ≤Maximum current consumption shown in table
•Current required at 24 VDC for service power supply in column (C) ≤Maximum current consumption shown in table
B. Calculate Maximum Total Power Supply (See the table below.)
•A×5VDC+B×24 VDC + C ×24 VDC ≤Maximum total power consumption shown in column (D)
•The amount of current/power that can be supplied to the Modules mounted in a Rack is limited by the capacity of the
Power Supply Unit.
•Design the system so that the total current consumption of the Modules does not exceed the maximum current for
each voltage group and the total power consumption does not exceed the maximum for the Power Supply Unit.

Note:1. When calculating current/power consumption in a CPU Rack — be sure to include the power required by the
CPU itself. When expanding the configuration, be sure to include the power required by the I/O Control Module.
2. When calculating current/power consumption in an Expansion Rack — be sure to include the power required by
the I/O Interface Module itself.

System Power, Expansion and I/O Allocations

I/O Allocations
JOverview
In CJ1 Series PLCs, I/O memory is allocated based on
the following: Basic I/O are automatically assigned words
based on position in the rack. In contrast, for Communica-
tions and Bus I/O, the user assigns the word allocations
within set ranges.
JAllocations to Basic I/O
Module Groups
Allocated words in the CIO Area: CIO 0000 to CIO 0079
Basic I/O Modules can be mounted to the CPU Rack and to
the Expansion Racks.
CPU Rack Allocations
Basic I/O Modules on the CPU Rack are allocated words
left to right (i.e., from the module nearest the CPU) starting
from CIO 0000. Modules are allocated as many words as
required in word units. Words can be reserved using
CX-Programmer Software.
Up to 10 modules
can be mounted.

An example of : words allocated from the left.
Modules with between 1 and 16 I/O points are allocated 1
word (16 bits), and modules having between 17 and 32 I/O
points are allocated 2 words (32 bits). For example, 8-point
Relay Modules are allocated 1 word, with bits 00 to 07
actually allocated to the I/O points.
Allocations to Expansion Racks
I/O allocation to Basic I/O Modules continues from the CPU
Rack to the Expansion Racks. Words are allocated from
left to right, and each module is allocated as many words
as it requires in word units— just like modules in the CPU
Rack. A Rack’s first word setting can be changed to any
word from CIO 0000 to CIO 9999.

JCompoBus/S and Special I/O
Allocations
When allocating I/O in CPU memory, CompoBus/S is
considered a Special I/O Module. These modules can be
mounted to the CPU Rack and Expansion Racks. Each
CompoBus/S Module is allocated ten words in the Special
I/O Module Area (CIO 2000 to CIO 2959). Refer to the
table provided to the right.
Note: During I/O allocation to Basic I/O Modules, Special
I/O Modules are ignored. (Slots containing Special
I/O Modules are treated as empty slots.)
JAllocations for All Networking and
Communications Modules — Except
CompoBus/S
Each CPU Bus Module is allocated 25 words in the CPU
Bus Module Area (CIO 1500 to CIO 1899).
CPU Bus Modules can be mounted to the CPU Rack or
Expansion Racks.
Each Module is allocated 25 words in the CPU Bus Module
Area according to its unit number, as shown in the table to
the right.
Note: CPU Bus Modules are ignored during I/O allocation
to Basic I/O Modules. The same unit numbers can be
used for Special I/O Modules and CPU Bus Modules.

3. These values are based on the condition that the Unit is cold-started at room temperature. Thermistor elements with current
suppression characteristics are used in the inrush current limiting circuits provided in the power supply. The inrush current may
exceed as much as twice these values if the ambient temperature is high or when the power supply is hot-started with insuffi-
cient cooling down time because the thermistors are not sufficiently cooled down. When selecting fuses or breakers for external
circuits, ensure a sufficient allowance for fuse or current detection characteristics.
