The EDS-308-MM-ST-T is an industrial-grade unmanaged Ethernet switch equipped with 6 copper and 2 fiber optic ports, tailored for demanding environments where reliability and rugged design are critical. Featuring two 100BaseFX multi-mode ST fiber ports and six 10/100BaseT(X) RJ45 ports, this model ensures dependable long-distance communication and strong resistance to electromagnetic interference.

With an extended operating temperature range from -40 to 75°C, the EDS-308-MM-ST-T is ideal for outdoor applications, factory automation, or power substations. A built-in relay output provides immediate alerts in the event of power loss or link failure, enhancing operational safety. Additionally, broadcast storm protection ensures network stability by preventing overload caused by faulty traffic.

Its durable metal housing allows for easy DIN rail or cabinet mounting. The unit is certified by FCC, UL, and CE, and approved for hazardous locations under Class 1 Div. 2 and ATEX Zone 2. Like all EDS-308 series models, it undergoes a 100% burn-in test to guarantee industrial reliability.
