HC900 Control System Architectures

Refer to the following manuals for more details on the various HC900 control system architectures.

Introduction to the Hardware

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. An HC900 Controller configuration with multiple controllers is
illustrated in Figure 4. This illustration includes key-numbers that identify components that are described in
Table 2. An HC900 Redundant Controller configuration with multiple I/O racks is illustrated in the below
figure.
