JB-TB-AT2020SH gas alarm controller with 1-8 channel

JB-TB-AT2020SH gas alarm controller 1:Sound and light alarm 2:Hbus or 4-20mA signal transmit 3:Competitive price 5:ISO9001&C

JB-TB-AT2020SH gas alarm Controller can network at most 8 combustible gas detectors and two programable outputs(gas valve or fan or both). It's with digital display timely displaying the amount of gas in the air. When the amount arrive to alarm valve, it will send out "Sound and Light" signal.

Feature:

1: Adopts HBUS four buses communication mode ,power wire and signal wire both use non-polarity design. And with automatic protection function to avoid damage caused by short –circuits.

2..Real-time gas concentration display and time display.

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

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

5.Two groups of programmable relay output module, can drive gas valve and AC fan which is lower 200W.

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.

4. Resistance to RF1/EMI interference

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

6. Support Three-Line system.

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

8. Optional backup power, consecutive changeover of main power and backup power supplies
