Emerson Ovation 1C31194G01 Valve Positioner Electronics Module

I/O Reference Manual Overview

The Ovation Distributed Control System provides modulating control, sequential

control, and data acquisition for a variety of system applications. This system

consists of a configurable mix of functional Input/Output (I/O) modules that

communicate on the I/O bus to the Ovation Controller.

I/O modules provide an interface between the Ovation Controller and the processes

in the plant. Ovation I/O modules are “plug-in” components with built-in fault

tolerance and diagnostics. They are able to operate on a wide range of signals and

perform a multitude of functions.

The Ovation I/O modules are locked into base units. These base units are housed in

the Controller cabinets where they are mounted on DIN rails and wired to the

appropriate field devices.

The standard modular components typically consist of the following:

• Electronics module

• Personality module

• Base Unit (containing the field terminations)

The relay output modular components consist of the following:

• Electronics module

• Base Unit (containing the field terminations)

This manual describes the I/O modules and their usage in the Ovation system.

Clear, Concise Operations

Providing plant operators with a clear, concise, easy to navigate window to the process is vital to successful operations. 

The Ovation Operator Workstation accomplishes that mission with crisp, high-resolution process graphics, 

built-in trending data, advanced system diagnostics displays, user-friendly help screens and a sophisticated alarm management and analysis package 

that prioritizes alarms to quickly isolate and address problems.

Ovation includes embedded applications such as fully coordinated boiler/turbine control, 

emissions monitoring, economic dispatch and fleet management for power projects. For water, 

wastewater, and renewable applications, Ovation incorporates a SCADA interface for wide-area monitoring and control,

seamless PLC integration, and comprehensive diagnostics programs. 

Coupled with Emerson’s PlantWeb™digital architecture, 

the Ovation system provides powerful technology for secure operations and best-in-class performance.

Tighter, More ReliableControl

The Ovation system is renowned for delivering precision control with outstanding performance. 

That precision begins with the Ovation Controller. With an Intel-based 

processor at its heart, the Ovation Controller provides full-redundancy to assure the reliability 

and security necessary for even the most demanding application. 

In addition to a comprehensive set of over 100 standard algorithms, 

Ovation also provides the ability to embed advanced control algorithms that leverage the ever expanding 

computing power of the Ovation Controller. 

This capability allows you to take control to a higher level by incorporating model predictive control and 

industry specific advanced applications to reduce process variability and optimize performance over the full range of plant operating conditions.
