Gas monitoring system with HBUS or 4~20mA communication

1:Gas monitoring system for combusitible & toxic gas 2:64 channels 3:Real-time display detector's number, concentration,etc

This  Gas Monitoring System can analyze  toxic and combustible gas,Temperature&Pressure signal. It can network at most 64 detectors and 4 programable outputs.It will real-time display the amount of gas in the air by Character display. When the amount arrive at alarm valve, it will send out "Sound and Light" signal.

Feature:

1.With multiwire communication interface and HBUS BUS interface,not only receive 4~20mA standard current signal(by our BD201 input module),but also can conduct distance expansion through HBUS interface.

2. Support combustible gas detector and toxic gas detector mix network or single alarm setting.

3.LCD display,can detect gas whose unit is %LEL,ppm,%VOL.

4. Automatic calibration and tracking sensor’s ageing state. Automatic tracking faults  ,and indicating faults location and type

5. Modifying detector's sensitivity and zero calibration with distance.

6 Built-in large capacity data memory, It can store fault records, alarm records, on/off records and event records by 3400 categories ,data is not lost after power-off.

7. Self-protection to over-concentration gas harm to sensor.

8.Resistance to RF1/EMI interference

9. Support Three-Line system.

10. Optional backup power, consecutive change over of main power and backup power supplies .

11. Support MODBUS communication, easily network with third party control system and fire-fighting system.

12. Can network with XG100 graphical monitoring system.
