Download PDF Download the ADAM-6520 data sheet.


ADAM-6520 ModuleThe ADAM-6520 family are 5-port industrial-grade switches with Ethernet connectivity and from 10 to 100 Mbps transfer rates. (Auto-negotiation). Just like 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. The Industrial grade ADAM-6520 has an operating temperature range of -40degC to 85degC This permits them to be functional in harsh environments. 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 for easy monitoring and diagnosis.
