Introduction
The EDS-208A Series 8-port industrial Ethernet switchessupport IEEE 802.3 and IEEE 802.3u/x with 10/100M full/half-duplex,MDI/MDI-X auto-sensing. The EDS-208A Series has 12/24/48 VDC (9.6to 60 VDC) redundant power inputs that can be connected simultaneouslyto live DC power sources. These switches have been designed for harshindustrial environments, such as in maritime (DNV/LR/ABS/NK), railwayside, highway, or mobile applications (EN 50121-4/NEMA TS2/e-Mark),or hazardous locations (Class I Div. 2, ATEX Zone 2) that comply withFCC, UL, and CE standards.
The EDS-208A switches are availablewith a standard operating temperature range from -10 to 60°C, or witha wide operating temperature range from -40 to 75°C. All models aresubjected to a 100% burn-in test to ensure that they fulfill the specialneeds of industrial automation control applications. In addition,the EDS-208A switches have DIP switches for enabling or disablingbroadcast storm protection, providing another level of flexibilityfor industrial applications.

Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link budget (dB) > dispersion penalty (dB) + total link loss (dB).
