Advantech ADAM-6520 Industrial Ethernet Switch

Advantech ADAM-6520 is a 5-port industrial unmanaged Ethernet switch designed for rugged automation networks. It provides five RJ-45 ports that support 10/100 Mbps Ethernet with auto-negotiation and auto MDI/MDI-X crossover, enabling simple, no-config network expansion for PLCs, sensors, and remote I/O. The unit is powered from a DC input of +10 to +30 V and includes 3000 VDC surge protection on the power line, helping guard connected equipment from voltage transients; Ethernet protection is built in as well, with 4,000 VDC ESD protection on standard models (the ADAM-6520L variant does not include this feature). Flexible mounting is a key design point, with options including DIN-rail, wall, and stacking to suit crowded control panels. The ADAM-6520 line is intended for industrial environments requiring reliable, low-maintenance switching, and it includes features like broadcast storm protection and a built‑in switch controller that handles auto-negotiation. Typical applications include factory PLC networks, machine automation, and the extension of Ethernet to remote I/O points where a compact 5-port switch is ideal.
