APPLICATIONVOGI
Industrial Automation Control System: Adapts to DCS/PLC system expansion, multi-device data interaction and real-time monitoring of production lines. Dual RS-422/RS-485 ports support half-duplex communication (1200 bps to 115.2 kbps) and redundant design ensures stability.
Energy and Power Industry: Applicable to power station equipment status monitoring, new energy inverter data acquisition and transmission and distribution network remote control. Wide temperature range (-20℃ to +70℃) and ISA G3 corrosion resistance certification meet the needs of harsh working conditions.
Chemical and Petroleum Refining: Used for equipment communication outside explosion-proof areas and production process data synchronization. The standard type has no explosion-proof design (suffix - S53), but built-in overvoltage protection and dual-port redundancy improve reliability in non-hazardous areas.
Environmental Protection and Water Treatment: Supports sewage treatment plant equipment linkage and emission monitoring data upload. Modbus protocol compatible and can be integrated into the DCS system. Industrial-grade protection ensures stable operation in humid or corrosive environments.
Rail transit and infrastructure: Adapt to subway signal system communication and railway equipment status feedback. High reliability design and modular structure support rail network distributed deployment and rapid response requirements.
Electronics and communications: Used for data center equipment monitoring and communication base station status management. High-density modular design supports multi-device access, and wide rate compatibility meets high-speed data transmission requirements.
