    CRGD-M1 is a new type gas control unit of the latest design with simple operation. It can combine with our many series gas detectors to make up an industrial gas detection system. It will display the concentration from each gas detector. When the gas concentration of any gas detector reaches or exceeds the preset alarm level, the controller will alarm with acoustic and light signals. Synchronously, the actuator will start up to drive the exhauster or cut off valve and other peripheral equipments, in order to prevent poisoning accident, explosion or fire. So this system can guarantee regular production and the security of the lives and property.


    1)   Chinese menu and English menu can be changed freely.

    2)   Used internal microprocessor with rich software function of signal collection from detectors, real-time data calculation, fault self-testing, power management, alarm display, alarm relay output, etc.

    3)   It can receive 4-20mA standard analog signal and RS485 digital signal input at the same time, with big capacity and kinds of communication protocol.

    4)   6 relay output with optional NO or NC (can be extended to 8 relay);

    5)   Wall-mounting, simple operation.
