Click on View [ Dimension & Mounting / wiring terminal ]
 
 ■ Characteristic:
 
Large LCD displays the status and concentration with white backlight 8 Programmable Linkage Output Interfaces, contact capacity is 10A 24VDC or 5A 250VAC

Easy to understand that users operating function

Modularization design method, The function that the whole software regulates

Standard signal input(4~20mA/Modbus) Automatically record the time of power on, power off, alarm and fault, keeping without power
Convenient operation mode and reliable touch screen    
 
 ■ Working theory:
 
      GN9000-B Gas Alarm Controller, sample & deal with the signal of 4~20mA or RS485 bus from detectors,transform to consistency of gas around detectors,display the value of gas consistency & all kinds of system status on LCD,gives out audio and visual alarm signal ,and output linkage controlling signal if fault or alarm occurs.. GN9000-B? gas control Controller can match the GN8010-C、GN8010-E、GN8020-C、GN8020-E、 GN8050、GN8010-R gas detector. And through RS485 or direct access to the DCS system, PLC or host computer communication systems, network management
