5-port 10/100 Mbps 5FE Unmanaged Ethernet Switch, Flexible mounting, -10-70°CTheAdvantech ADAM-6520 is a 5-port industrial-grade switch with Ethernet connectivity. It can be mounted by DIN rail, Wall and Stack. Solid industrial-grade design assures reliable operation in common application areas like: semi-conductor factories, inventory control environments, assembly lines, manufacturing and many more. TheADAM-6520 supports a wide voltage range of 10 – 30 VDC over the terminal block, and 3,000 VDC surge (EFT) protection ensures that over-voltage is no concern. Wide operating temperature range from -10 ~ 70°C. The six inclusive LED indicators make troubleshooting of the modules easier. Each port has a pair of LEDs that indicate link status and port activities. This easily informs users of any collisions, the link status, power failure and data receipts for immediate on-site diagnosis.
