The ADAM-6521 is an industrial-grade Ethernet hub for infrastructure networking solution in industrial Automation environment. It allows users to cost-effectively expand their industrial network with ease. The ADAM-6521 consists of one fiber optic and four RJ-45 ports. With fiber optic, you can prevent noise interference from the system and transmission distance up to 2 km. The design is focused on industrial-grade reliability and stability. Thus, the ADAM-6521 is especially suited for industrial environments with Ethernet networking needs, e.g. semi-conductor factories, inventory control environments, assembly lines, production and more.
