the packaged controller's maximum available bus current, you are within the expansion I/O limit
of your packaged controller.
Example of Expansion I/O Calculation
In this example, these expansion I/O modules and bus current draws are planned for use with the
1769-L23E-QBFC1B packaged controller.
Planned Expansion I/O Module
1769-OV16 Sink Output Module
1769-IF4 Analog Input Module
1769-ECR End Cap
Total Bus Current Draw
(1) The maximum bus current draw specification for each Compact I/O™ module is available in the Compact I/O Selection Guide, publication
1769-SG002. This publication also provides further explanation of and a table for the calculation of Compact I/O power supply requirements.
The total bus current draw of the Compact I/O modules (310 mA) is less than the total available
bus current of the packaged controller (450 mA). These planned expansion I/O modules are
within the limits of the 1769-L23E-QBFC1B packaged controller.
