Hardware Components

This section contains general descriptions of each of the major components of the HC900 system. For
environmental specifications, refer to the section on Pre-Installation Planning.
HC900 Controller Rack
An HC900 Controller ("local rack") is
shown in Figure 4. As indicated in this
figure, the Controller Rack includes:
1. a Rack, available in 4- 8-, or 12-slot
versions
2. a Power Supply
3. a Controller Module
4. Grounding bars (for I/O wiring; optional)
5. Input/Output modules.
6. I/O Terminal Blocks
I/O Expansion Rack (C50 CPU only)
I/O expansion ("remote") racks, shown in Figure 5, are available to accommodate additional input/output
modules, and/or to enable location of I/O modules close to the process and remote from the controller.
Most of the components in an I/O expansion
rack are identical to those used in the Controller
Rack. The only difference is the Scanner
Module (item 3) that occupies the same rack
location as the Controller Module in a
Controller Rack. An I/O expansion rack
includes:
1. a Rack, available in 4- 8-, or 12-slot versions
2. a Power Supply
3. a Scanner Module
4. Grounding bars (for I/O wiring; optional)
5. Input/Output modules
6. I/O Terminal Blocks
