Current Consumption Tables
The amount of current/power that can be supplied to the Modules mounted in a Rack is limited by the capacity of the Rack’s Power
Supply.
Consider the Current/Power Consumption When Designing the System
•
The total current consumption of the Modules must not exceed the maximum current for each voltage group.
•
The total power consumption must not exceed the maximum for the Power Supply
CPU Racks and Expansion Racks
The following tableshows the maximum currents and power that canbe supplied by Power Supplies on CPU Racks and Expansion
Racks (both CS1 Expansion Racks and C200HW Expansion I/O Racks).
Note: 1. When calculating current/power consumption in a CPU Rack, be sure to include the power required by the CPU Rack and CPU themselves.
2. Likewise, be sure to include the power required by the Rack itself when calculating the current/power consumption in an Expansion Rack.

SYSMAC BUS Slave Racks
The following table shows the maximum current and power supplied by Power Supplies in SYSMAC BUS Slave Racks.
Note: Be sure to include the power required by the Rack itself when calculating current/power consumption.
