MicroLogix 1500 System Expansion Worksheet - Example
The following example is provided to illustrate system expansion validation. The
table below accounts for the amount of 5V dc and 24V dc current consumed by
controller, expansion I/O, and user supplied equipment. The worksheet on the
next page shows how to validate your specific configuration. Current consumed by
the Base Units, Memory Modules, and Real Time Clock Modules has already been
factored into the calculations below.
NOTE
For an electronic version of the worksheet, visit the MicroLogix
web site. On the Internet, go to http://www.ab.com/micrologix.
Enter MicroLogix 1500; go to Tools and Tips, Expansion I/O
System Qualifier.

(1) These are optional accessories. Current is consumed only if the accessory is installed.
(2) Current for the 1761-NET-AIC may be supplied from the controller communications port, as seen in this example, or from an external 24V dc source. No current is consumed
from the controller when an external source is used. The current for a 2707-MVH232 or 2707-MVP232 MicroView™ Operator Interface is supplied from the controller
communication port, if directly connected.
