Note: This price is for display only, and the actual price is subject to the quotation!

Chicheng QB2000ABus based 32 channel 4-20mA gas alarm host controller， The QB2000 gas alarm controller consists of an alarm monitor and gas detector, which can be mixed with multiple gas detectors. It is easy to install and network, and can achieve measurement, display, and public alarm control of 8, 16, or 32 physical quantities.

The Chicheng QB2000A (bus system) gas alarm host controller system uses a 32-bit embedded microprocessor as the control unit, high-performance catalytic gas sensing elements or high-precision imported electrochemical sensors as detection detectors, with high sensitivity and fast response speed. When the detected gas concentration in the ambient air reaches or exceeds the preset alarm value, the controller immediately emits an audible and visual alarm to remind timely safety measures to be taken, and controls the driving of exhaust or other peripheral devices to prevent explosions, fires, and poisoning accidents, thereby ensuring the safety of life and property.

Features:

High definition industrial color screen with high sensitivity touch screen, resolution 1024 * 600;

Equipped with self checking function, configurable backup power supply (optional function), automatic switching between main and backup power, and various parameters can be freely set in the system menu;

Equipped with alarm record query and real-time reminder functions, the alarm channel number, concentration, alarm time, and mute function can be directly queried through the menu and status bar;

Up to 48 channels are available for selection

Standard Modbus RS-485 signal input, 4-20mA available

16GB massive data storage, TF card data export, data printing

RTU 433MHz wireless transmission, GPRS wireless transmission

• RS485、RS232、 Multi channel 4-20mA signal, TCP/IP network port output

• Split screen display function, displaying relevant data of 8 channels of devices on each screen

It can be used for gas safety detection and alarm in places that require fire prevention, explosion prevention, and poisoning prevention, such as oil exploration and extraction, oil and gas transportation, refining, metallurgy, power plants, chemicals, oil depots, liquefied gas stations, mines, tunnels, underground pipelines, etc.
