Product Description
The HT308RI-2R-2SFPG industrial grade serial switch is a special model developed by our company for the industrial control field, which adopts the industry's leading technical standards and supports up to two 485/232/422 three-in-one serial servers, each supporting four TCP or UDP session connections; and supports multiple operating modes: TCP Server, TCP Client, UDP, TCP auto, Realcom, Advanced TCP Server and Advanced UDP modes. The industrial serial switch provides stable and reliable Ethernet transmission with high quality design and reliability. It provides users with bandwidth-efficient, reliable fibre optic network solutions for Ethernet data switching, aggregation and remote optical transmission. The product features small size, fanless, low power consumption, high reliability, good stability and easy maintenance.
The HT308RI-2R-2SFPG industrial-grade Ethernet switch product adopts mature technology and open network standards, adapts to low and high temperatures, is highly resistant to electromagnetic interference, salt spray resistant, shock and jitter resistant, and is equipped with redundant dual DC power supplies or AC/DC220V single power supplies to provide a redundancy mechanism for critical equipment that needs to be kept always connected. It can also operate in the standard operating temperature range of -40 to 75°C. The industrial switch supports DIN rail or wall mounting and has an IP40 protection rating, making it perfect for harsh environments such as industrial networks, intelligent transport systems (ITS) and also for many military and utility market applications where environmental conditions exceed commercial product specifications.
