The Gas Alarm Controller is designed to work with standard 4-20mA current signals and RS485 bus signals for control and communication. It uses a high-performance microcontroller for reliable and stable operation. The controller connects to gas detectors to continuously monitor toxic and hazardous gases in the environment. It displays real-time gas concentration readings and supports communication with an upper computer via RS485. Users can set two-level alarm thresholds. When gas concentration exceeds the limit, the controller triggers audible and visual alarms based on the alarm level. Data logs, alarm records, system logs, and alarm channels can be queried via the menu. It also provides relay output to control external devices such as exhaust systems.
