CC-PDOB01 Experion系列C输入/输出模块

Experion Series C input/output chassis-less mounted modules and field level network gateways provide the physical connection between an automation system and the process when used with the C300 Controller. Input/Output Modules and field terminations are combined in the same area. The Input/Output Modules are plugged into Input /Output Termination Assemblies to eliminate the need for a separate chassis to hold the electronics assemblies.
C300 Controller
The C300 Controller is constructed using the Series C form factor that employs an Input Output Termination Assembly (IOTA) and an electronics module which mounts and connects to the IOTA. One C300 Controller contains all of the control functionality and the communications functions with plug-in modules.
The C300 Controller may operate in both non-redundant and redundant configurations. Redundant operation requires a second identical controller and connecting cables, which is the typical configuration.
The C300 Controller is connected to the associated I/O hardware by a pair of I/O Link Interface cables The table below identifies the C300 Controller components and its associated components. TheC300 Controller supports non-redundant and fully redundant operation. Redundancy is built in to the controller, so that just adding another controller and a redundancy cable; a redundant controller pair is achieved.
Note that the ‘CC’ designation on the model number indicates the printed wiring boards are conformally coated for additional protection from the environment, (CU = uncoated).

A High Level Analog Input Module supports both high level analog and HART inputs. Analog inputs are typically 4- 20mA DC for both traditional and HART devices. HART data can be used for status and configuration. HART data, such as the secondary and tertiary variables, can also be used as process control variables.

The Series C modules comprise:
 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.
