As an enhanced iteration of the AT0602 series, the GTYQ-AT0602A delivers stronger compatibility and scalability for modern industrial safety monitoring. It features a rugged explosion and dust ignition proof structure, ensuring safe operation in explosive hazardous areas. The three-color alarm light clearly identifies normal, fault and alarm states, offering intuitive and fast status recognition for on-site operators. Running on AC220V power supply, it supports independent stable operation, suitable for both new construction and retrofitting projects. Infrared remote control realizes non-intrusive debugging, making daily setup and maintenance more convenient and safer. The digital sensor assembly can be replaced without on-site calibration, maintaining high detection accuracy while reducing maintenance workload. With IP66 protection, it adapts to harsh environments with dust, humidity and water splashing. It is equipped with a high-brightness digital tube display and supports offline valve detection, wireless solenoid valve connection and automatic power-off valve cut-off. Direct interlock with industrial solenoid valves ensures rapid risk response. Furthermore, it supports IoT cloud platform centralized control and is equipped with multi-standard expansion ports for optional functional modules, satisfying diversified and customized monitoring demands.
