Industrial grade configuration
Support GPS positioning function
The ZHL4921G version supports GPS positioning with a positioning accuracy of about 10 meters. *Note: For this version, it is recommended to consult customer service before placing an order.
Support configuration software docking
ZHL4921 has an RS485 interface, which supports the standard Modbus RTU/TCP protocol. The configuration software can directly read data and command control ZHL4921 through the RS485 interface.
Support multiple networking methods
ZHL4921 supports networking functions, supporting one-to-one, many-to-one networking, etc. It is very practical for the needs of certain special scenarios.
Support local logical operations
Support active collection
Support automatic collection and proactive reporting. The collection instructions and collection cycle can be dynamically modified. Reduce server processing flow.
Support analog automatic calibration threshold reporting
Industrial IoT gateway application
Because the industrial Passerelle pour l'internet des objets has the characteristics of easy installation, no wiring, plug and play, etc., it is suitable for environmental monitoring systems, computer rooms, machine station power, factory machinery and equipment, production line operating status monitoring systems, low-voltage power distribution monitoring systems, and electric energy data Wireless monitoring and early warning application scenarios such as monitoring systems and production information collection systems.
At the same time, it can be used for signal collection and transmission; such as atmospheric environment monitoring signal collection and data transmission; agricultural greenhouse environmental monitoring signal collection and data transmission; breeding environment monitoring signal collection and data transmission; pharmaceutical and food storage environment monitoring signal collection and data transmission. Production process signal collection, MES (Manufacturing Execution System) signal collection, and data transmission of manufacturing and processing enterprises; environmental monitoring of hazardous chemical sites.
