Introduction
The EDS-205/208 series of industrial Ethernet switches are entrylevel industrial 5 and 8-port Ethernet switches that support IEEE
802.3/802.3u/802.3x with 10/100M, full/half-duplex, MDI/MDIX autosensing RJ45 ports. The EDS-205/208 switches are rated to operate
at temperatures ranging from -10 to 60°C, and are rugged enough for

any harsh industrial environment. The switches can be easily installed
on a DIN-Rail as well as in distribution boxes. The DIN-Rail mounting
capability, wide operating temperature, and the the IP30 housing with
LED indicators make the plug-and-play EDS-205/208 switches easy to
use and reliable.
