CompactLogix Packaged Controllers 5
Publication 1769-IN082A-EN-P - July 2008
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.
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.
Parts (included with the packaged controller)
These components are included with your CompactLogix packaged controller.
Parts (optional, not included with the packaged controller)
In addition to the parts included with the packaged controller, you may choose to
use these components specific to your application.
