Zetron MIC2000-M 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.

●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 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 (up to 32 channels) 4-20mA input signal, at the same time can be connected to 255 channels RS485 input signal, more channels input signal can be customized, the controller and the 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.
