EDS-205A/EDS-208A Series

EDS-205A/EDS-208A Series

5 and 8-port unmanaged Ethernet switches

The EDS-205A/208A series are 5 and 8-port Industrial Unmanaged switch 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/LR/ABS/NK), rail wayside, highway, or mobile applications(EN 50121-4/NEMA TS2/e-Mark), or hazardous locations (Class I Div. 2, ATEX Zone 2) that comply with FCC, UL, and CE standards.


The EDS-205A/208A Industrial Unmanaged 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.
