• Redundant dual 12/24/48 VDC power inputs
• IP30 aluminum housing
• Rugged hardware design well suited for hazardous locations (Class 1 Div. 2/ ATEX Zone 2), transportation (NEMA TS2/EN 50121-4/e-Mark), and maritime environments (DNV/GL/LR/ABS/NK)
• -40 to 75°C operating temperature range (-T models)
Certifications
The EDS-208A Series 8-port industrial Ethernet switches support 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 (9.6 to 60 VDC) redundant power inputs that can be connected simultaneously to live 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-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-208A switches have DIP switches for enabling or disabling broadcast storm protection, providing another level of flexibility for industrial applications.
