Zetron Cheap RS485 8 Channels Relay Output Alarm Control Panel

Product Description

MIC2000 Gas Alarm Controller

The gas alarm controller is a centralized alarm controller for gas concentration monitoring and leakage. The power source is directly powered by the mains grid or battery. This alarm controller receives RS485 signal and 4-20mA, and temporarily can only receive RS485 signal output by our company's new online detector. If you need to connect to the standard RS485 signal of other manufacturers, please contact our company for confirmation. One gas alarm controller can be connected to 120 channels of bus
system RS485 output gas detectors and 8 channels of 4-20mA output gas detectors, and more input channels can be customized.

Product Parameters

 

·  3.5"  HD  color  screen  display,  switchable  between  Chinese  and  English  operation  interface (default Chinese interface).
·  Can be connected to various gas detectors, temperature and humidity transmitters, pressure transmitters, wind speed transmitters, dust detectors and other 4-20mA signals.
·  Units available: PPM, LEL%, Vol%, mg/m3, ug/L, PPHM, ºC , RH%, Pa, kg, PSI, m/s
·  4-20mA and RS485 can be input at the same time; data output supports standard MODBUS protocol options: 8-channel 4-20mA output, Ethernet module, PC monitoring software for upper computer, RS485/RS232 converter, USB-RS232 connection cable (PC without serial port needs this option)
·  Modular structure design, the standard channel is 1 channel (maximum 32 channels) 4-20mA input signal, at the same time, it can connect 255 channels RS485 input signal, more channels input signal can be customized, the controller and controller can communicate with each other.
·   Gas  alarm  controller   has  data   recording  function,  standard   large-capacity  storage,   more large-capacity can  be customized. Storage time  interval  can  be  set arbitrarily,  recording time, concentration value, alarm information, etc. It can be set to record real-time concentration or only alarm information, and the default setting is only alarm information. Support local view all records, selective view records and delete records.
·  Three display modes can be switched: displaying the concentration of 6 channels per screen, displaying the concentration of a single channel in large font cycle, real-time curve, automatic cycle or  manual  cycle  between  channels  can  be  switched, whether  to display the  maximum  value, minimum value, gas name can be set, and historical record graph can be viewed.
·  Gas alarm controller with computer monitoring function can be connected to a computer to continuously monitor the real-time concentration through the host computer software 24 hours a day,  automatically  store  data  on  the  computer,  computer  alarm  (need  to  be  equipped  with speakers), or through the host computer software to read the records stored in a probe or all probes and data analysis, can display the maximum value, minimum value, average value, historical curve, real-time curve and other functions, can export data or printing
· The remote transmission function of the gas alarm controller allows the controller to transmit the real    time    concentration    of    the    sensors    on    site    via    cable     (within    2000    meters).
