Product Description

Gas Alarm System Gas Alarm Controller 8 Channels Gas Detector Controller

Product Description:

The DN1000 series gas alarm controller can be applied to the measurement and control of various signals, such as 4-20mA signals, RS-485 signals, and TCP/IP network interface devices.
The electronic circuit adopts advanced high precision micro-controller processing technology, which makes the controller work stably with high measuring precision and strong generality.
The system adopts Andriod operating system. Therefore, it has user-friendly operation interface, powerful system function. Operating the system menu through buttons, the main display screen displays gas detector concentration value, alarm information, fault information and other information.

 

Key Features

•  standard 4-20mA signals input, supports up to 8 detectors input
•  standard Modbus RS-485 signal input, supports up to 8 detectors input
•  standard TCP/IP network port device input
•  32G mass data storage,TF card data export, data printing
•  2 relays outputs as standard,each relay out can control one jet fan
•  RS485, multi-channel 4-20mA signal, TCP/IP network port output
•  split-screen display function, each screen display related data of 8 channel
