Function Module Power Requirements
The Function Modules get power by being connected into a string of Logic Assemblies. As a result, it
will reduce the maximum number of Logic Assemblies that can be connected into one string. This is
shown in the following chart, which is based on a 3 foot cable from the power supply to the first Logic
Assembly, and 3 foot maximum zone spacing.
Number of Function Modules
0-2
3-7
8-12
Maximum # of Logic Module Assemblies per string
33
32
31
The Function Modules require 10mA of current at 24 VDC. This needs to be considered, as it will reduce
the total number of Logic Modules that can be connected to one Class 2 power supply to some quantity
less than 53.
