Product Details

Description

Gas Detector Controller is a reliable and practical gas monitoring solution tailored for medium-scale industrial applications. Featuring a compact and reasonable structural design, it has one management card that can support up to 10 discrete-wired detectors and control a maximum of 10 channel cards, each running independently and stably without interfering with each other, ensuring the accuracy and reliability of monitoring data. The management card is equipped with a clear TFT LCD display, and each channel card can independently display gas concentration values in real time, enabling quick and accurate identification of abnormal gas conditions. It supports Analog 4-20mA 2/3/4 wire detectors, allowing flexible combination of multiple detectors according to on-site needs, and each detector can be set with independent parameters to adapt to different monitoring environments. Built-in RS485 ports are compatible with multiple communication protocols, facilitating data transmission and integration with the existing monitoring system. The optional wireless gateway enables convenient IoT transmission, realizing remote data viewing and management, which perfectly meets the monitoring needs of medium-sized sites with diverse detector configurations and high stability requirements.

High Capacity

Supports up to 10 discrete-wired detectors and 10 independent channel cards with no limits for expansion.

TFT LCD Display

Features a 2.8" TFT LCD on the management card, with independent real-time concentration displays on each channel.

Flexible Compatibility

Compatible with standard Analog 4-20mA 2/3/4 wire detectors with independent parameter settings.

IoT & RS485

Built-in RS485 ports and optional wireless gateway (NB / 4G) for remote data viewing and integration.
