Reference Table for Maximum Current Consumption
The following table shows the maximum currents and power that can be supplied by Power Supply Units on CPU Racks
and Expansion Racks.
Note:1. When calculating current/power consumption in a CPU Rack — be sure to include the power required by the
J Example Calculations
In this example, the following modules are mounted to a CJ1 Series CPU Rack with a CJ1W-PA205R Power Supply Unit.

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
A × 5 VDC + 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.
2. When calculating current/power consumption in an Expansion Rack — be sure to include the power required by
CPU itself. When expanding the configuration, be sure to include the power required by the I/O Control Module.
the I/O Interface Module itself.
