RT-HES8G Series

8G-port full Gigabit unmanaged Ethernet switches
The RT-HES8G series are equipped with 8 Gigabit Ethernet ports, making them ideal for applications that demand high bandwidth. The RT-HES8G 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 RT-HES8G series includes 2 models: one with an operating temperature range from -10 to 60 °C, and the other one with an extended operating temperature range from -40 to 85 °C. Both models are subject to a 100% burn-in test to ensure that they fulfill the special needs of industrial automation control applications
