AO2000-LS25 Advance Optima Continuous Gas Analyzers
The electronics module incorporates the system controller withl/O modules and l/O boards.
The system controller caries out the following functions:Processing and communicating the measured values suppliedby the analyzer module sensor electronicsCompensating measured values, e.g. cross sensitivitycorrectionControlling system functions, e.g. calibration
Display and control functions
Controlling associated systems, e.g. gas supplyCommunicating with external systems
The system controller communicates with the other functionalunits of the gas analyzer (e.g. the l/O boards and analyzermodules) via the system bus.
Interfaces for controlling associated systems and for communi-cating with external systems are located on the system controller(Ethernet 10/100BASE-T interface) and on the l/O modules andl/O boards.
The l/O modules are attached and directly connected to thesystem controller board, There are four types of l/O modules:Analog output modules have two analog outputs.Digital l/O modules have four digital inputs and four digitaloutputs.
Modbus modules have one RS485 and one RS232 interface.Profibus modules have one RS485 and one MBP interface
