8C-PCNT02

Honeywel’s C300 Controller provides powerful and robust control for the distributed control system (DCS).The C300 is a node in operating Honeyell’s field-proven deterministic Control Execution Environment (CEEcore software. The CEE software provides a superior control execution and scheduling environment. Controlstrategies for each controller node are configured and loaded through a common Control Builder, an easy andintuitive engineering tool.
In addition to a standard and robust library of pre-built function blocks and algorithms, the C300 Controller alsosupports Custom Algorithm Blocks (CABs). Custom Algorithm Blocks are similar in purpose and structure to thestandard function blocks that are distributed with Control Builder. However, CABs have user-defined algorithmsand data structures, allowing custom tailored strategies to be developed to specific requirements
The C300 controller shares its hardware design with the Series 8 lO, offering an innovative design that reducesfootprint and installation and maintenance costs. The C300 controller module is mounted on the C300 inputOutput Termination Assembly (l0TA). The C300 lOTA contains only passive devices such as FTE addressswitches.Figure 1 below depicts the lOTA components.

Definitions
• Input Output Termination Assembly (IOTA): An assembly that holds the IOM and the connections for field wiring;
• Input Output Module (IOM): A device that contains most of the electronics required to perform a specific I/O function. The IOM plugs onto the IOTA.
Features
All Series 8 components feature an innovative design that supports enhanced heat management. This unique look provides significant reduction in overall size for the equivalent function.
The unique features of Series 8 I/O include:
• I/O Module and field terminations are combined in the same area. The I/O Module is plugged into the IOTA to eliminate the need for a separate chassis to hold the electronics assemblies
• Two level “detachable” terminals for landing the field wiring in the enclosure, providing easier plant installation and maintenance.
• Field power is supplied through the IOTA, with no need for extra power supplies to power the field devices and the associated craft wired marshalling
• Redundancy is accomplished directly on the IOTA without any external cabling or redundancy control devices, by simply adding a second IOM to an IOTA
• For both IOM and IOTA, coated (module numbers starting with 8C) and uncoated (module numbers starting with 8U) options are provided. Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes. Coated IOM and IOTA are recommended when electronics must withstand harsh environments and added protection is necessary.
