Advantech ADAM-6521/ST is an industrial-grade Ethernet switch with a fiber optic port that makes it possible to expand industrial networks fast and cost-effectively. ADAM-6521/ST has 1 fiber port and 4-RJ-45 ports. With fiber optics, you can prevent noise interfering with your system and implement transmission distances up to 15 km. Advantech ADAM-6521/ST supports a wide voltage range of 10 ~ 30 VDC over the terminal block, and 3,000 VDC surge protection (EFT) to protect it from being damaged by over-voltage. A wide operating temperature range from -10 to 65° C (14 ~ 149° F), makes it functional in harsh operating environments. Six inclusive LED indicators make troubleshooting easier. Each port has a pair of LEDs that indicate link status and transmission speed. This function conveniently informs users of any collisions, the link status, power failure and data receipts for immediate on-site diagnostics.
