The EDS-309 Series offers a cost-effective and robust solution for industrial Ethernet networking. These unmanaged switches provide 9 total ports – 6 copper (10/100BaseT(X)) and 3 fiber optic ports (100BaseFX, multi-mode SC or ST) – designed for flexibility and long-distance communication in harsh environments.

Engineered for rugged industrial use, the EDS-309 switches are ideal for demanding applications that require extended temperature operation (-40 to 75°C for -T models) and compliance with hazardous location standards such as Class 1 Div. 2 and ATEX Zone 2.

An integrated relay output alerts users to power loss or port disconnection, enhancing system safety. Broadcast storm protection prevents network failures due to excessive traffic. With auto-negotiation, Auto MDI/MDI-X, and full/half duplex support, the switches integrate seamlessly into existing networks.

Compact metal housings, DIN rail or cabinet mounting, and 100% burn-in testing ensure reliability in mission-critical systems.
