GN9000-A Single Loop Gas Control System

Click on View [ Dimension & Mounting / wiring terminal ]
 ■ Characteristic:
4 digits high-light LED 2 Programmable Linkage Output Interfaces/Two groups programmable output interface interaction
Humanized operation interface Calibration function of the entire software
Input & Output of International Standard Signal(4~20mA/Modbus) Modularization design method
 ■ Working theory:
     GN9000-A Single Loop Gas Control System consist of two components:gas controller and gas detector. After sampling and dealing with the 4~20mA international standard signal outputed from the detector, the gas concentration of relevant detection point will be transformed and displayed on nixietube, as well as different status of the system. In case of failure or alarm, the controller will send out relevant acousto-optical signal and output corresponding linkage control signal.GN9000-A single loop gas control system can match the GN8010-C、GN8010-E-A、GN8020-C、GN8020-E gas detector, applying to installation program of small-scale monitering system.
