Dedicated fan control using the 4100-7401 24-Point I/O is similar to control using Relay IAMs
and 6-Point I/O Modules, except that the 4100-7401 module is used for both control and feedback.
This module communicates with the 4100U/4100ES Master over the RUI communications, and
offers the added advantage that all I/O is supervised. The figure below shows the equivalent
interconnects for applications using a 24-Point I/O Module.
