The EDS-308 Series from Moxa offers rugged, unmanaged 8-port Ethernet switches designed for industrial networking applications. These devices provide a cost-effective solution for network connectivity in environments requiring high reliability and temperature resilience.

A key feature is the integrated relay output that issues an alarm when a power failure or port interruption occurs. The switches also include broadcast storm protection to prevent network failures.

Designed for use in harsh environments such as those defined by Class I Div. 2 and ATEX Zone 2, these switches are available in standard temperature range versions (-10 to 60 °C) and wide temperature versions (-40 to 75 °C for -T models). Easy installation on DIN rails or in distribution boxes is supported.
