Product Description

Description

Gas Detector Controller is an upgraded small-scale gas monitoring solution, specially developed for users who need to upgrade existing small-scale gas monitoring systems. It is equipped with a Chinese/English LCD display that supports two-language switching, making debugging and operation more convenient, and can clearly display the installation location of each device, effectively improving on-site operation and management efficiency. The lightweight enclosure is made of high-grade V0-rated flame-retardant material, which has excellent flame-retardant and anti-corrosion performance, ensuring safe and stable operation in various small-scale environments. Compared with the SE model, it has stronger compatibility, supporting both XBUS 2/4 wire and analog 4-20mA communication, which can adapt to different types of detectors on the market. Built-in RS485 and TTL ports support multiple communication protocols, facilitating smooth connection with the original monitoring system. The built-in IoT module realizes direct IoT transmission, enabling remote monitoring and data management, making it an ideal choice for users who need to upgrade existing small-scale gas monitoring systems with simple operation, high compatibility and intelligent functions.
