MIC4000 Explosion-proof Controller

The MIC4000 explosion-proof controller is a gas concentration monitoring and leakage centralized alarm controller. The power supply is directly supplied by the mains power grid or the storage battery. This alarm controller receives RS485 signal and 4-20mA, and temporarily can only receive the RS485 signal output by the company\'s new online detector. If you need to connect to the standard RS485 signal of other manufacturers, please contact our company for confirmation. A gas alarm controller can be connected to 120 bus RS485 output gas detectors and 8 4-20mA output gas detectors. More input channels can be customized.
