Product Description

MIC2000 Gas alarm controller




The gas alarm controller is a centralized alarm controller for gas concentration monitoring and leakage. The power supply is directly supplied by the mains power grid or the battery. The alarm controller receives RS485 signal and 4-20mA. For the time being, it can only receive the RS485 signal output by the company's new online detector. If you need to access the standard RS485 signal from other manufacturers, please contact our company for confirmation. YIhe gas alarm controller can be connected to 120 bus system RS485 output gas detector and 8 4-20mA output gas detector, more input channels can be customized. 




● 3.5-inch HD color screen display, Chinese and English operation interface can be switched (default Chinese interface)


● Can connect all kinds of gas detector, temperature and humidity transmitter, pressure transmitter, wind speed transmitter, dust detector and other 4-20mA signal,


● Units available: PPM, LEL%, VOL %, mg/m3, UG /L, PPHM, ℃, RH%, Pa, kg, PSI, m/s


4-20mA and RS485 can be input at the same time; Data output supports the standard Modbus protocol


Optional: 8 channel 4-20 ma output, Ethernet module, PC computer monitoring software, RS485 / RS232 converter, USB and RS232 cable (no serial port the computer need to be selected)


● Modular structure design, standard channel for 1 (up to 32 channels) 4-20mA input signal, at the same time can be connected to 255 channels RS485 input letter


No., more channel input signal can be customized, controllers and controllers can communicate with each other.


● The gas alarm controller has the function of data recording, the standard capacity is 100,000 pieces, and the larger capacity can be customized. The storage time interval is set arbitrarily, Recording time, concentration value, alarm information, etc., can be set to record real-time concentration or only record alarm information, the default setting is to record only alarm information. Support SD card storage or U disk storage, support the machine to view all records, selectively view records, delete records.


● Three display modes can be switched: each screen displays 6 channels of concentration, large character body circulation display single channel of concentration, real-time curve, between each channel. The automatic cycle or manual cycle can be toggled, and the maximum value, minimum value, gas name can be set, and the historical record curve can be viewed.


● Gas alarm controller with computer monitoring function, can be connected to the computer through the upper computer software 24 hours continuous monitoring of real-time concentration on the computer. Automatic storage of data, computer alarm (need to be equipped with speakers), or through the upper computer software read a probe or all the probe stored records and data analysis, can display the maximum value, minimum value, average value, historical curve, real-time curve and other functions, data can be exported or printed


● Gas alarm controller remote transmission function, the controller can put the real-time concentration of the field probe through the wire (within 2000 meters)


Optional: Ethernet transmission or wireless transmission function (2km, 5km, unlimited distance optional), through 2-core data line (wired transmission),


Local area network, Internet or wireless transmission network will upload the data to the monitoring center, environmental protection bureau, other monitoring equipment, and then through the upper computer software for data display, storage, analysis, or use the communication protocol custom read data.




Signal input: 1 ~ 32 channels 4 ~ 20mA, at the same time RS485 input, can connect 255 probes


Output signal: Ethernet, RS485 (standard Modbus protocol), 4-20mA (4-way, 8-way optional)


Display range: Numbers 0 ~ 99999
