The GTYQ-XP4000B is an optimized version of the XP4000 series, focusing on enhanced visual alarm and intelligent interconnection for industrial safety scenarios. It features a robust explosion and dust ignition proof structure, guaranteeing safe operation in explosive hazardous locations. It supports dual-channel relay output with separate high and low alarm configurations, enabling accurate hierarchical early warning. The detector integrates XBUS 2-wire and 4-20mA analog communication, delivering high compatibility for system integration and retrofitting. Its digital sensor assembly can be replaced without on-site calibration, and the IP66 protection grade ensures stable performance under harsh conditions. It is equipped with a built-in two-stage sound-light alarm and a high-brightness digital tube display for clear status indication. It supports the extended Modbus protocol for seamless connection with PLC and DCS systems. A standard three-color alarm light interface is added to achieve more intuitive status distinction. This model is suitable for intelligent safety monitoring systems requiring clear visual alerts and stable digital communication.
