Zetron 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.
