The combustible gas alarm controller is applied in places where combustible gases are produced, transported, stored, and filled. It collects the concentration of combustible gases in the air detected by point type combustible gas detectors (4-20mA signals).
When the set alarm value is reached, corresponding alarm signals and control signals are output to prompt on-site personnel to take timely safety measures. DCS, fire graphics and other systems can be connected, and external equipment such as exhaust fans and solenoid valves can be started to ensure personnel and equipment safety and prevent accidents caused by combustible gas leakage.
The controller is suitable for non explosion proof places such as fire control rooms and control centers.
