The EDS-309-3M-SC-T is a rugged 9-port unmanaged Ethernet switch equipped with six 10/100BaseT(X) RJ45 ports and three 100BaseFX multi-mode SC fiber optic ports. Designed for high-reliability industrial applications, this model supports a wide operating temperature range from -40 to 75°C.

The SC fiber ports offer reliable long-distance communication and strong resistance to electromagnetic interference, making this switch ideal for factory automation, energy infrastructure, or transportation systems. Auto-negotiation, full/half duplex, and Auto MDI/MDI-X support ensure effortless integration into existing Ethernet infrastructures.

A built-in relay output provides immediate alerts in the event of power failure or port disconnection, while broadcast storm protection safeguards the network from traffic overloads.

Built with a durable metal housing and engineered for DIN rail or cabinet installation, the EDS-309-3M-SC-T complies with industrial certifications including FCC, UL, CE, and is rated for hazardous locations (Class 1 Div. 2, ATEX Zone 2). Each unit undergoes a 100% burn-in test to ensure long-term operational stability.
