Introduction
The EDS-208A series industrial Ethernet switches with 8 ports support IEEE 802.3 and IEEE 802.3u/x with 10/100M full/half duplex, MDI/MDI-X auto-sensing. The EDS-208A series features redundant power inputs of 12/24/48 VDC (9.6 to 60 VDC) that can be connected simultaneously to live DC power sources. These switches are designed for harsh industrial environments, such as maritime applications, railway stations, highways, mobile applications, or hazardous locations, complying with FCC, UL, and CE standards.

The EDS-208A switches are available with a standard operating temperature range of -10 to 60 °C or with an extended operating temperature range of -40 to 75 °C. All models undergo a 100% burn-in test to ensure they meet the specific requirements of industrial automation control applications. Additionally, the EDS-208A switches feature DIP switches to enable or disable broadcast storm protection, providing an extra layer of flexibility for industrial applications.
