The EDS-308 Series from Moxa consists of high-performance unmanaged Ethernet switches with 8 ports, designed specifically for industrial networking applications. These devices offer a reliable and economical solution for tough environments, including ATEX Zone 2 and Class 1 Division 2 hazardous locations.

A built-in relay output allows for alarm notifications in the event of a power failure or port interruption, enhancing overall network resilience. Additionally, broadcast storm protection helps prevent network overloads.

EDS-308 switches are available in models for both standard temperature ranges (-10 to 60 °C) and wide temperature environments (-40 to 75 °C for -T models). They support convenient DIN-rail or cabinet installation and are rigorously tested to meet industrial automation demands.
