X921216-8C-E is a 10G L3 28 Port switch introduced by Shenzhen Xallcom Technology Co., Ltd.. It is a core aggregation type industrial ring network switch product specifically designed for the industrial control field. The product supports rich three-layer protocols, static routing, RIP, VRRP, OSPF protocols, as well as rich network management functions. It can provide stable and reliable Ethernet transmission, with high-quality design and reliability. We can provide users with efficient bandwidth, reliable fiber optic network solutions for Ethernet data exchange, aggregation, and remote optical transmission. This product has the characteristics of small size, fanless, low power consumption, high reliability, good stability, and easy maintenance. Adopting mature technology and open network standards, it adapts to low temperature and high temperature, has strong resistance to electromagnetic interference, anti salt spray, earthquake resistance and anti shake, and is equipped with redundant dual DC or AC power supply, which can provide redundancy mechanism for key equipment that needs to be always connected. It can also operate within the standard working temperature range of -40 to 80 ° C. The hardware adopts fanless, low-power, and wide temperature and pressure design. Through strict testing in accordance with industry standards, it can adapt to industrial site environments with strict requirements for EMC, and has reliable industrial grade design such as vibration and impact resistance, IP40 protection, etc. It can be widely applied in industries such as energy, transportation, industrial production, environmental protection, and military industry.
