Product Performance
Protocol conversion capability is strong: It supports bidirectional conversion of multiple protocols such as Modbus RTU/TCP and DF1, enabling seamless data interaction between serial devices (e.g., inverters, sensors) and Ethernet systems (e.g., SCADA, HMI) without programming, with data transmission delay ≤10ms.
Communication stability is high: 2.5kVrms electrical isolation for serial ports and surge protection for Ethernet ports effectively suppress electromagnetic interference and voltage fluctuations in industrial environments, ensuring continuous communication without packet loss; dual Ethernet ports support link redundancy to avoid communication interruption caused by single-point faults.
Configuration and maintenance are convenient: It integrates a web graphical configuration interface, allowing port parameters, protocol mapping and alarm threshold settings via a browser without installing dedicated software; real-time diagnostic functions can monitor port links, power supply and data transmission status, and fault information is synchronously fed back via LEDs and the web interface, reducing troubleshooting time.
System compatibility is wide: It adapts to mainstream industrial serial devices (PLCs, instruments, actuators) and Ethernet systems (DCS/SCADA from brands such as Rockwell, Siemens, GE), supports multi-master access, and a single device can connect 4 serial devices simultaneously and access Ethernet without additional expansion modules.
Environmental adaptability is excellent: The wide temperature range of -10℃ to +60℃ covers most industrial scenarios; IP30 dust-proof design and vibration resistance allow direct deployment in workshop control cabinets or beside equipment, enabling stable operation without additional protective measures.
