The EDS-205A/208A series are 5 and 8-port industrial Ethernet
switches that support IEEE 802.3 and IEEE 802.3u/x with 10/100M
full/half-duplex, MDI/MDI-X auto-sensing. The EDS-205A/208A
switches provide 12/24/48 VDC (9.6 to 60 VDC), 18 to 30 VAC
redundant power inputs that can be connected simultaneously to live
AC/DC power sources. These switches have been designed for harsh
industrial environments, such as in maritime (DNV/GL) or hazardous
locations (Class I Div. 2/ATEX) that comply with FCC, TUV, UL, and CE
standards.

The EDS-205A/208A 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. All models are subjected to
a 100% burn-in test to ensure that they fulfill the special needs of
industrial automation control applications. In addition, the EDS-
205A/208A switches have DIP switches for enabling or disabling
broadcast storm protection, providing another level of flexibility for
industrial applications.
