Introduction

The EDS-G308 series are equipped with 8 Gigabit Ethernet ports and up to 2 fiber optic ports, making them ideal for applications that demand high bandwidth. The EDS-G308 switches provide an economical solution for your industrial Gigabit Ethernet connection, and the built-in relay warning function alerts network managers when power failures or port breaks occur. The EDS-G308 series includes 2 models: one with an operating temperature range of 0 to 60°C, and the other one with 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.
