ABB AO2000 Series Advance Optima Continuous Gas Analyzers

ABB AO2000 Series Advance Optima Continuous Gas Analyzers

Overview

Advance Optima AO2000 Series is a line of modules used for  process gas analysis.

The product line consists of the following modules:

• Analyzer Modules  

• Pneumatics Module  

• Electronics Module  

• I/O Modules and I/O Boards  

• Housing with Display and Control Unit  

• System Bus

The modules can be arranged in various ways to form single or  multiple analyzer systems.

An analyzer unit (see example 1 on page 5) usually consists of:  

• One analyzer module  

• the electronics module  

• the power supply  

• the housing with display and control unit

A multiple analyzer system (see example 2 on page 5) in its  maximum stage of extension consists of:  

• Four analyzer modules handling up to six sample components  

• The pneumatics module  

• The electronics module  

• The required number of power supplies  

• The required number of housings  

Pneumatics Module

The pneumatics module contains the following elements when  fully equipped:

• One or three solenoids to control test gas supply  

• One or two disposable elements for fine filtration  

• One gas supply pump with coarse filter and capillary  

• One or two flow monitors

Electronics Module

The electronics module incorporates the system controller with  I/O modules and I/O boards.

The system controller carries out the following functions:  

• Processing and communicating the measured values supplied  by the analyzer module sensor electronics  

• Compensating measured values, e.g. cross sensitivity  correction  

• Controlling system functions, e.g. calibration  

• Display and control functions  

• Controlling associated systems, e.g. gas supply  

• Communicating with external systems

The I/O modules are attached and directly connected to the  system controller board. There are four types of I/O modules:  

• Analog output modules have two analog outputs.  

• Digital I/O modules have four digital inputs and four digital  outputs.  

• Modbus modules have one RS485 and one RS232 interface.  

• Profibus modules have one RS485 and one MBP interface  (not intrinsically safe).

Examples of I/O module and I/O board applications include:  

• Output of measured values  

• Output of status and alarm signals  

• Calibration control  

• Control of external solenoid valves and pumps  

• Measurement range switching and feedback  

• Supply of external analyzer current or status signals  

• Supply of status signals from peripherals
