Moxa EDS-208A Series – Compact 8-Port Industrial Ethernet Switches for Harsh Environments

The Moxa EDS-208A Series features compact unmanaged 8-port Ethernet switches designed for industrial automation and critical infrastructure. Supporting both copper and fiber connections (SC/ST, multi-mode or single-mode), these switches offer deployment flexibility across transportation systems, marine applications, hazardous areas (Class 1 Div. 2, ATEX Zone 2), and railway environments.

Encased in a rugged IP30-rated aluminum housing and equipped with dual redundant 12/24/48 VDC power inputs, the EDS-208A ensures high reliability even in extreme temperatures ranging from -40 to 75 °C (for -T models). DIP switches provide additional customization options such as broadcast storm protection.
