1. Series 8 I/O Purpose
1.1 Overview
Series 8 I/O modules, along with I/O Termination Assemblies (IOTAs), perform module
diagnostics input and output scanning and processing on all field I/O data and events. To
allow a more efficient use of Controller resources, I/O processing is performed separately
from control processing functions so that:
 I/O sample rates are completely independent of I/O quantity, controller loading,
processing, and alarming
 Allows more efficient use of advanced Control Processor capability, and
 Provides for future I/O expansion
1.2 What is I/O?
Series 8 I/O
The Experion Series 8 I/O modules are an expanding family of traditional and special
function input/output signal interface devices. They support local software configuration.
These I/O modules share the same form factor as the C300 Controller and reside on the
same type of common mounting system as other Series 8 components.
