The EDS-309 Series offers robust 9-port unmanaged Ethernet switches designed for demanding industrial applications. With six 10/100BaseT(X) RJ45 copper ports and three 100BaseFX fiber optic ports (SC or ST multi-mode), the EDS-309 models provide a versatile solution for reliable long-distance network connectivity.

A built-in relay output alerts network engineers in the event of power failure or port disconnection, making the EDS-309 ideal for industrial automation environments. Broadcast storm protection ensures network stability even under faulty traffic conditions. All standard Ethernet features are supported, including auto-negotiation, Auto MDI/MDI-X, and full/half duplex modes.

Designed for extended temperature ranges down to -40°C and up to 75°C (-T models), the EDS-309 series complies with FCC, UL, and CE certifications and is approved for hazardous locations (Class 1 Div. 2 and ATEX Zone 2). The units can be easily mounted on a DIN rail or inside a distribution cabinet.

Every switch undergoes a comprehensive 100% burn-in test to ensure consistent performance in mission-critical operations.
