JH-Z128 flammable gas alarm
JH-Z128 type flammable gas alarm controller (hereinafter referred to as controller) is suitable for flammable gas production, transportation, storage, filling and other places. It collects combustible gas in the air detected by point type flammable gas detector (RS485 digital signal). concentration.
When the set alarm value is reached, the corresponding alarm signal and control signal are output, prompting the operator to take safety measures in a timely manner, and at the same time, external devices such as exhaust fans, solenoid valves, etc. can be activated to ensure the safety of personnel and equipment and prevent flammable An accident occurred after a gas leak.
The controller is suitable for non-explosion-proof control rooms, duty rooms, and corridors.
