Introduction
The external control port of the controller is rich, user can choose the access port freely, and connect the on-site detection and alarms can be performed with simple settings.
The system is mainly used in the need to detect so many gases, when the concentration of the gas higher than the pre-set value, the relay will drive a series of alarm actions, such as alarm, discharge wind, tripping, etc.
The controller is non-explosion-proof and should be installed in a safe area.
