Overview
This section provides a description of each of the major components that can be included in an HC900 Controller
physical configuration, and indicates some of the methods by which they can be combined.
Components
The Honeywell HC900 Process Controller includes a set of hardware modules that can be combined and configured
as required for a wide range of small to medium process control applications.
Some of the modules are required in all configurations. Others are optional; they are selected as appropriate to
provide optional functions and/or to “size” the system, either in initial planning, or in modifying and/or expanding
the system to meet changing requirements.
