Communications Specifications
2-6 Unit Current Consumption
The amount of current/power that can be supplied to the Units mounted in a
Rack is limited by the capacity of the Rack’s Power Supply Unit. Refer to the
following tables when designing your system so that the total current con-
sumption of the mounted Units 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.
2-6-1 CJ-series CPU Racks and Expansion Racks
The following table shows the maximum currents and power that can be sup-
plied by Power Supply Units in CPU Racks and Expansion Racks.
When calculating current/power consumption in a CPU Rack, be sure to
include the power required by the CPU Unit itself, as well as the I/O Control
Unit if one or more Expansion Racks is connected. Likewise, be sure to
include the power required by the I/O Interface Unit when calculating current/
power consumption in an Expansion Rack.
