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

The EDS-208A Series by Moxa provides reliable unmanaged switches with up to 8 Fast Ethernet ports and optional fiber connections (100BaseFX, SC/ST, multi-/single-mode). Designed for industrial applications including transportation, energy, marine, and hazardous zones, these switches deliver robust network connectivity with compliance to global safety and environmental standards.

The IP30-rated aluminum housing, dual 12/24/48 VDC power inputs, wide operating temperature (-40 to 75 °C for -T models), and advanced features like DIP switch-configurable broadcast storm protection make these switches ideal for critical automation environments.
