The EDS-G308 Series includes rugged, unmanaged full Gigabit Ethernet switches featuring 8 ports, with optional models offering 2 combo SFP slots for fiber connections. These switches are designed for high-bandwidth industrial networking applications and offer reliable and economical connectivity in environments exposed to electromagnetic interference or requiring long-distance transmission.

Built-in relay warning functions notify network managers of power or port failures, while DIP switch settings allow easy activation of broadcast storm protection, jumbo frame support, energy-saving mode, and SFP speed switching. Wide-temperature models ensure optimal operation even in harsh conditions down to -40 °C.
