Overview

GDB15 gas alarm controller is a 485 output signal controller developed by our company, which has the characteristics of good stability, high accuracy and intelligent parameter setting. The external control port is rich, the user can freely choose the type of detector and access port, and can carry out on-site monitoring and alarm through simple setting and wiring.

The controller is mainly used in the occasion of monitoring combustible gas, showing the numerical indicator of the gas to be tested. When the indicator of a certain gas to be tested on site does not meet the set standard, the system will automatically carry out a series of alarm actions, such as alarm, exhaust, trip, etc. (according to different Settings of the user).
