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/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.
Introduction
EDS-205A/208A Series
Specifications
5 and 8-port unmanaged Ethernet switches
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.
