ADAM-6520 is a 5-port industrial-grade switch with Ethernet connectivity and from 10 to 100 Mbps transfer rates. (Auto-negotiation). Justlkie any other product in the ADAM family, ADAM-6520 can be mounted in three different ways: 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. All modules support a wide voltage range of +10 ~ 70°, while ADAM-6520 from -40 ~ 85°. This permits them to be functional in harsh environments. The six inclusive LED indicators make troubleshooting of the modules easier. Each prot 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.
