Overview 
The EDS-205A/208A series of industrial Ethernet switches are entry-
level industrial 5 and 8-port Ethernet switches that support IEEE 802.3, 
IEEE 802.3u, and IEEE 802.3x with 10/100M, full/half-duplex, and 
MDI/MDIX auto-sensing. 
The EDS-205A/208A series provides 12/24/48 VDC (9.6 to 60 VDC) 
redundant power inputs. The switches are available with a standard 
operating temperature range from -10 to 60°C, or with a wide 
operating temperature range from -40 to 75°C, and IP30 metal housing 
makes them rugged enough for any harsh industrial environment. 
To provide greater versatility for use with applications from different 
industries, the EDS-205A/208A also allow users to enable or disable 
broadcast storm protection with DIP switches on the outer panel. 
The EDS-205A/208A switches can be easily installed with DIN-Rail 
mounting as well as distribution boxes. The DIN-rail mounting 
capability and IP30 metal housing with LED indicators make the plug-
and-play EDS-205A/208A switches reliable and easy to use.
