HONEYWELL 8C-PCNT02 51454363-275 Series 8 Controller and I/OSpecification

HONEYWELL 8C-PCNT02 51454363-275 Series 8 Controller and I/OSpecification 

Honeywell’s C300 Controller provides powerful and robust control for the distributed control system (DCS). The C300 is a node in operating Honeywell’s field-proven deterministic Control Execution Environment (CEE) core software. The CEE software provides a superior control execution and scheduling environment. Control strategies for each controller node are configured and loaded through a common Control Builder, an easy and intuitive engineering tool. In addition to a standard and robust library of pre-built function blocks and algorithms, the C300 Controller also supports Custom Algorithm Blocks (CABs). Custom Algorithm Blocks are similar in purpose and structure to the standard function blocks that are distributed with Control Builder. However, CABs have user-defined algorithms and data structures, allowing custom tailored strategies to be developed to specific requirements. The C300 controller shares its hardware design with the Series 8 I/O, offering an innovative design that reduces footprint and installation and maintenance costs. The C300 controller module is mounted on the C300 Input Output Termination Assembly (IOTA). The C300 IOTA contains only passive devices such as FTE address switches. Figure 1 below depicts the IOTA components.

This document provides technical information to configure the Series 8 I/O. The following Series 8 I/O items are included in this document. 

• TC/RTD • Analog Input – Single Ended 

• Analog Input with HART – Single Ended 

• Analog Input with HART – Differential 

• Analog Output 

• Analog Output with HART 

• Digital Input Sequence of Events (SOE) 

• Digital Input, 24 VDC 

• Digital Input Pulse Accumulation 

• Digital Output, 24 VDC 

• DO Relay Extension Board 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.

The Series 8 inherits the innovative styling of Series C. 

This styling includes features to facilitate the effective use of control hardware in a systems environment. These features include: 

• Vertical mounting allows for more effective wiring since most field wiring applications require entry from the top or bottom of the systems cabinet. 

• An “information circle” allows for a quick visual cue to draw the Maintenance Technician’s eyes to important status information. 

• “Tilted” design allows for effective heat management within the cabinet enclosure. Since Series 8 allows for a significant increase in cabinet density, an effective heat management system is critical for high system availability. 

• Input and output circuits are protected from shorts to alleviate the need for in- line fusing, reducing installation and maintenance costs Series 8 IOTAs combine multiple functions into a single piece of equipment: 

• Single and redundant configurations 

• On-board termination of process signals 

• On-board signal conditioning 

• On-board connection to appropriate networks (FTE, I/O LINK) 

• Field power distribution without external marshalling 

• IOM plugs into the IOTA and receives power from the IOTA 

• The IOTA receives its power through cables from header board. Series 8 I/O Sizing In virtually all configurations, the C300 controller and Series 8 I/O provides useful, maintainable process equipment connections in a smaller footprint than traditional rack based systems. Installing Series 8 I/O modules contributes to overall total installed cost savings. IOTA sizes vary based on the application. In general, an analog module has 16 points and resides on a 6-inch (152mm) IOTA for non-redundant applications and a 12-inch (304mm) IOTA for redundant applications. A discrete module has 32 points and resides on a 9-inch (228mm) IOTA for non-redundant applications and a 12-inch (304mm) IOTA for redundant applications. Specific information on the size of a particular module can be found in the Model Number Table. I/O Module Functions
