The JB-TB-AT2020DX Gas Detector Controller is an intelligent control device for gas detection systems, realizing centralized monitoring and management of detectors. It features a 4.3-inch TFT color LCD with an intuitive graphic interface, enabling easy viewing of data and parameter setting. Supporting detector installation location labeling and independent alarm point settings for zones/objects, it improves emergency disposal efficiency. Adopting a two-wire non-polarized design compatible with four-wire communication, it simplifies wiring and deployment. Its rainproof structure protects internal components, while the boost function solves system instability from backup voltage drop. An optional wireless gateway enables IoT remote monitoring. Equipped with a digital tube display, manual buttons, a high-capacity AC contactor, and two sets of programmable relays, it suits diverse indoor/outdoor scenarios. With stable performance and complete functions, it provides reliable control for gas detection systems.
