Controller Overview:
The CMC-600KZ series flammable/toxic gas alarm monitoring host is a flammable/toxic alarm controller independently developed by our company with practical functions and easy operation. It can be used together with our company’s flammable/toxic gas detectors to form an industrial gas alarm system.
The controller can carry multiple gas detection detectors and centrally control multiple points at the same time. Through the use of the detector, and the controller microcontroller processes various data uploaded by the detector, it finally completes the functions of data display, output control, etc. Output RS485 signal, can be connected to PLC, host computer, etc.;
Functional Features:
☆Display the concentration of the detected gas
☆Fault alarm
☆LCD display
☆Receive 485 signals
☆Equipped with a high-performance microprocessor that is easy to operate
☆Automatically open the fan and solenoid valve
☆Output RS485 signal, can be connected to PLC, host computer
Technical parameters of the controller：
1. Detection object: flammable / toxic gas / O2
2. Measuring range: 0-100%LEL (combustible gas);

Product installation：
◆ Matching detectors: GT-CMC600 series flammable/toxic gas detectors;
◆ Wiring method with gas detector: four-wire 4*1.0mm2;
◆ The gas alarm controller is a non-explosion-proof product and should be installed in the monitoring room or indoor safe area or in an environment without explosive gas;
◆ Choose a reasonable installation height for installation, place it horizontally, and it can be easy to operate. It should not be too low to avoid accidental damage to people.
