• 8G-port full Gigabit unmanaged Ethernet switches

The EDS-G308 switches are equipped with 8 Gigabit Ethernet ports, respectively, and up to 2 fiber optic ports (one for EDS-G205-1GTXSFP series and two for EDS-G308-2 SFP series), making them ideal for applications that demand high bandwidth. The EDS-G308 switches provide an economical solution for your industrial Gigabit Ethernet connections, and the built-in relay warning function alerts network managers when power failures or port breaks occur. In addition, the add-on 4-pin DIP switches can be used for controlling over the functions of broadcast protection, jumbo frame, IEEE 802.3az energy saving and 100/1000 SFP speed switching (EDS-G205-1GTXSFP series only) is ideal for easy on-site configuration for any industrial automation application. Two models are available in this series. One model has an operating temperature range of -10 to 60°C, and the other model has an extended operating temperature range of -40 to 75°C. Both models undergo a 100% burn-in test to ensure that they fulfill the special needs of industrial automation control applications. The EDS-G308 switches can be installed easily on a DIN-rail or in distribution boxes.
