1:Tray type gas detecting system 2:For toxic&combustible gas detectors,temperature&pressure signal 3:4-20mA,Expandable channe

 Gas monitor, GAS DETECTING SYSTEM ,GAS DETECTOR ,for toxic and combustible gas,Temperature&Pressure signal

Feature:

1.Standard 4U tray-type metal construction,You may add Control card and channel card by will.

2.Communication between Control card and channel card is HBUS signal, while for channel card and detector is 4~20mA signal.

3.Monitoring combustible gas detector, toxic gas detector, flame detector, pressure sensor and temperature sensor, etc.

4.Control card adopts centralized monitoring, Channel card independently display.Two systems run at the same time to make sure each channel is in order.

5.Perfect alarm (threshold) value setting, can separately set pre-alarm, low alarm, high alarm for any address range or any type of detectors

4. Detectors sensitivity and zero calibration can be remotely modified .

5. Resistance to RF1/EMI interference.

6.Control card and channel card respectively have several groups of passive output ,easy to achieve remote

  logic control and system integration;

7.Automatic protection function, can automatically protect bus 's short -circuit;

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

9.Modular design, easy to maintain and debug.

10.Control card adopts TFT LED character display, a whole new and efficient operation system ,stable running, Channel card can independently real-time display detector 's information

11.Equips with intelligentized power supply system, perfect under voltage, over-current protectio function
