EDS-205A Series
5-port compact unmanaged Ethernet switches
Features and Benefits
• 10/100BaseT(X) (RJ45 connector), 100BaseFX (multi/single-mode, SC or ST
connector)
• 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), and maritime
environments (DNV/GL/LR/ABS/NK)
• -40 to 75°C operating temperature range (-T models)
Certifications
Introduction
The EDS-205A Series 5-port industrial Ethernet switches support IEEE 802.3 and IEEE 802.3u/x with 10/100M full/half-duplex, MDI/MDI-X autosensing. The EDS-205A 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-205A 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 switches have DIP switches for enabling or disabling broadcast storm protection, providing another level of
flexibility for industrial applications.

Note: When connecting a single-mode fiber transceiver, we recommend using an
attenuator to prevent damage caused by excessive optical power.
Note: Compute the “typical distance” of a specific fiber transceiver as follows: Link
budget (dB) > dispersion penalty (dB) + total link loss (dB).
