The EDS-305 Series includes rugged 5-port unmanaged Ethernet switches tailored for industrial use. These switches provide a cost-effective network solution, specifically designed to meet the demands of challenging environments where reliability and resilience are paramount.

A key feature is the built-in relay output for fault detection—alerting network administrators when a power failure or port interruption occurs. Additionally, the switches support broadcast storm protection to maintain network stability.

With wide operating temperature support, especially in -T models (from -40 to 75 °C), the EDS-305 Series is ideal for use in harsh zones such as those regulated by ATEX Zone 2, Class I Div. 2, and IECEx. Installation is quick and easy via DIN rail or optional wall mount.
