Overview
About the HMS-HRM-G16R4F8BT
A multi-port, high-standard industrial managed Ethernet switch developed by Hepda for industrial Ethernet networks. It adopts industry-leading technical standards and provides stable and reliable Ethernet transmission. Housed in a rack-mount aluminum case, it adds 4 × 10 Gigabit Ethernet ports and supports Layer 3 routing to facilitate the deployment of applications across networks.
Industrial Ethernet switches in this range are equipped with redundant power, and resist high and low temperatures, electromagnetic interference, vibration and shock. They operate at -40 to 75°C in 19” rack mounts that meet IP40 protection — suited to harsh environments such as utility markets and industrial networking.
