The EDS-305 Series from Moxa offers a compact and economical 5-port unmanaged Ethernet switch solution for industrial applications. Designed to withstand harsh environments, these switches are compliant with Class I Div. 2, ATEX Zone 2, and IECEx standards. A built-in relay output alerts users to power failures or port disconnections – a valuable diagnostic tool in critical systems. The built-in broadcast storm protection enhances network stability by preventing congestion from faulty devices.

The EDS-305 Series supports a wide temperature range of -40 to 75 °C (T models) and features a durable IP30-rated metal housing. Easy DIN-rail installation and 100% burn-in testing ensure reliable operation in demanding automation environments.
