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)/18 to
30 VAC redundant power inputs that can be connected simultaneously to
a live AC/DC power source. 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.
