Non-dedicated fan control using the 24-Point I/O is similar to control using a Relay IAM
or 6-Point I/O Module, except that the 4100-7401 24-Point I/O Module is used for both control
and feedback. This module communicates with the 4100U/4100ES Master over the RUI
communications SLC, and offers the added advantage that all I/O is supervised, so no restrictions
on module placement are required. The figure below shows the equivalent interconnects for
applications using a 24-Point I/O.
