Overview

Advance Optima AO2000 Series is a line of modules used for

continuous process gas analysis.

The product line consists of the following modules:

 Analyzer modules

 Pneumatics module

 Electronics module with system controller and I/O modules

 Housing with display and control unit

 System bus

The modules can be arranged in various ways to form single or

multiple analyzer systems.

The electronics module, power supply and housing with display

and control unit are also collectively referred to as the “central

unit”.

Laser analyzer module

Each analyzer module consists of the sensor and associated

electronics having its own processor. The analyzer modules are

linked to the system controller via the system bus. The laser

analyzer module is linked to the central unit via Ethernet.

The analyzer modules are supplied with 24-VDC from an integral

power supply or an external unit.

The electrochemical oxygen sensor is available as an option in

combination with an analyzer module.

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

The pneumatics module is always associated with an analyzer

module and installed in the same housing as the analyzer

module.

Electronics module, interfaces

The electronics module incorporates the system controller with

the I/O modules.

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 system controller communicates with the other functional

units of the gas analyzer (e.g. the analyzer modules) via the

system bus.

Interfaces for controlling associated systems and for communi

cating with external systems are located on the system controller

(Ethernet 10/100/1000BASE-T interface) and on the I/O modules.

The I/O modules are attached and directly connected to the

system controller board. There are six types of I/O modules:

 Profibus modules have one RS485 and one MBP interface.

 Modbus modules have one RS485 and one RS232 interface.

 Digital I/O modules have four digital inputs and four digital

outputs.

 2-way analog output modules have two analog outputs.

 4-way analog output modules have four analog outputs.

 4-way analog input modules have four analog inputs.

Examples of I/O module 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

 Feed of current or status signals from external analyzers

 Feed of status signals from peripherals

Housing

The housing is available as a 19-inch (model AO2020) or wall

mount (model AO2040) unit with IP20 or IP54 protection.

IP54 housing versions can be purged. The display and control

unit is located on the front panel of the housing when the

electronics module is installed.

System bus

The gas analyzer’s functional units are interconnected via the

system bus. The system bus structure is linear with a maximum

length of 350 meters. Only one electronics module with up to

five I/O modules should be connected to a system bus structure.

Connection of sample gas conditioning modules

The SCC-F sample gas feed unit and the SCC-C sample gas

cooler can be connected to the gas analyzer via the system bus

by means of an I/O board installed in the sample gas feed unit.

Thus it is possible to display, monitor and control individual

sample gas conditioning functions in the gas analyzer such as

cooler temperature or condensate and flow status. For further

information please refer to the “System components and

accessories for sample gas conditioning” data sheet.
