The EDS-308 series offers robust and economical 8-port Ethernet switches tailored for industrial applications. These unmanaged switches are designed to perform reliably in harsh environments, making them an ideal solution for industrial automation networks where dependability and quick setup are crucial.

A key feature of the EDS-308 series is the integrated relay warning function, which alerts engineers to power failures or broken links—enhancing network safety. Additionally, broadcast storm protection is included to ensure stable performance, while essential Ethernet features like auto-negotiation, full/half duplex, and Auto MDI/MDI-X are supported.

Multiple model variants are available, including configurations with multi-mode or single-mode fiber ports (SC or ST), and extended-distance options supporting up to 80 km. The -T models operate reliably in extreme temperatures from -40 to 75°C. All models are DIN rail or distribution box mountable.

With certifications for hazardous locations (Class 1 Div. 2 and ATEX Zone 2), and compliance with FCC, UL, and CE standards, these switches are built for demanding industrial environments. Every unit is burn-in tested to ensure long-term reliability.
