Chapter 9
Calculate Power Consumption in an Additional Bank
Use this table to calculate power consumption in an extra bank.
IMPORTANT
In extra banks, you can install I/O modules to the left side, right side, or both
sides of the power supply.
The system design determines how to use the following table.
Table 30 - Module Power Consumption Calculation for an Additional Bank

Module Current Requirements
Calculated Current =

Total Current Required for Bank if Modules Are Installed on Both Sides of the Power Supply
(1)
:
(1) This number must not exceed the power supply current capacity for the bank.
(2) This number must not exceed the power supply current capacity for this side of the bank.
(3) You can install up to eight modules in additional banks if the power supply distance ratings for the modules validate the system design.
