Overview of FLEX I/O and Your Analog Module
Overview Read this chapter to familiarize yourself with configurable features on the FLEX
I/O High Density modules. The following table lists where to find specific
information in this chapter.
The FLEX I/O System FLEX I/O is a small, modular I/O system for distributed applications that
performs all of the functions of rack-based I/O. The FLEX I/O system contains
the following components shown below:
• adapter/power supply – powers the internal logic for as many as eight I/O
modules
• terminal base – contains a terminal strip to terminate wiring for two- or
three-wire devices
• I/O module – contains the bus interface and circuitry needed to perform
specific functions related to your application
