GN9000-S Gas Alarm Controller
  
Click on View [ Dimension & Mounting / wiring terminal ]
 
 ■ Characteristic:
 
4 digits high-light LED Easy to understand that users operating function
2 Programmable Linkage Output Interfaces/Two groups programmable output interface interaction Input & Output of International Standard Signal(4~20mA/Modbus)
Modularization design method    
 
 ■ Working theory:
 
    GN9000-S Gas Alarm Controller, sample & deal with the signal of 4~20mA or Mod-bus from detectors,transform the signal to consistency of gas around detectors,display the value of gas consistency & all kinds of system status on LED,give out alarm signal of light & sound ,and output linkage controlling signal if fault or alarm occur.
    GN9000-S can work not only with GN8010-C, GN8010-E, GN8020-C, GN8020-E detectors, but also with every kind of instruments, which output standard 4-20mA current. So GN9000-S can be applied to the large centralized monitor system and our company can customize GN9000-S Gas Alarm Controller according the requirements of customers.
