XO-AC2011D Combustible Gas Alarm Host

Product Features:

Dual HBUS four bus communication interface with automatic protection function to prevent damage to the controller caused by any short circuit of the circuit during construction or use.

Adopting LCD liquid crystal display and a fully Chinese graphical operation interface, it has three display modes: list, curve, and column, and can simultaneously monitor gases in units of% LEL, ppm, and% VOL.

Adopting an ARM and AVR dual processor design architecture, it responds faster and runs more stably.

Automatic calibration and tracking of sensor aging status; Automatic fault monitoring function, which can indicate the location and type of the fault.

Remote sensitivity correction and zero point adjustment of detectors can be performed without the need for on-site calibration using large gas distribution equipment.

Built in large capacity data storage, capable of classifying and storing fault records, alarm records, power on/off records, and event records, without loss during power outages.

Anti RFI/EMI interference.

Can be used for the renovation of three wire split line equipment.

Provide two multifunctional output communication interfaces (COM1, COM2), which can realize controller interconnection, TCP/IP interface, communication with the upper computer, and connection to micro printers.

Fully modular system design, convenient for debugging and maintenance of large systems.

Optional power supply with seamless switching between main and backup power and working status indication function.
