Description
GDB8 gas alarm controller is an instrument developed by our company that can process multiple sets of (4~20) mA signals at the same time.
GDB8 gas alarm controller has the characteristics of good stability, high accuracy and intelligent parameter setting. It has rich external control ports. Users can freely choose the type and access port of the attached sensor, and can conduct on-site detection through simple settings and alarm. The current version of the system has integrated an alarm horn, 4 branch line interfaces, 2 RS485 signal interfaces, et 3 sets of passive switching signal output ports.
The GDB8 gas alarm controller system is mainly used in occasions where combustible gases need to be detected. It displays the numerical indicator of the gas to be detected. When the indicator of a certain gas to be detected on site does not meet the set standards, the system will automatically perform a series of Alarm actions, such as alarm, exhaust, trip, etc.. (different according to different user settings).
