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 auto-sensing. 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/LR/ABS/NK), rail wayside, highway, or mobile applications (EN 50121-4/NEMA TS2), or hazardous locations (Class I Div. 2, ATEX Zone 2, IECEx) 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 and Quality of Service, providing another level of flexibility for industrial applications.

The EDS-205A Series is also compliant with PROFINET Conformance Class A (CC-A), making these switches suitable for PROFINET networks.

Note: When using a 40 km single-mode fiber transceiver over short distances, we highly recommend installing an attenuator to prevent damaging the transceiver due to excessive optical power. Note: To reach the "typical distance" of a fiber transceiver, the Link Budget (dB) should be greater than the combined Dispersion Penalty (dB) and Total Link Loss (dB).
