High-Quality JB-TB-AT2020LH Gas Detector Controller Suppliers, Factory

Product Description

Description
Gas Detector Controller is a high-efficiency gas monitoring device specifically designed for large-scale industrial scenarios. It adopts a scientific modular design to achieve flexible configuration, with one management card capable of supporting up to 32 discrete-wired detectors and controlling a maximum of 8 channel cards simultaneously. Each channel card operates independently without mutual interference, effectively realizing real-time independent display of gas concentration values, allowing operators to grasp the gas status of each monitoring point at a glance.
The management card is equipped with a high-definition TFT LCD display, which ensures clear and intuitive data reading even in complex industrial environments. It fully supports 4-20mA 2/3/4 wire detectors, compatible with multiple detector combinations, and allows independent parameter setting for each detector to meet diverse monitoring needs. Built-in RS485 ports support various mainstream communication protocols, facilitating seamless connection with the upper monitoring system. In addition, an optional wireless gateway is available for IoT transmission, enabling remote monitoring and data management, making it an ideal choice for large-area gas monitoring projects that require stable, efficient and intelligent operation.
