16 ports 10/100M Ethernet + 4  ports Gigabit (SFP slot) Managed Industrial Ethernet Switch.

IT-ES7120-IM-4GS is an industrial grade, managed and redundancy Ethernet switch. It provided 16 Ethernet ports and 4 Gigabit (SFP slot) ports. SW-Ring™ is an arithmetic designed as a rapid redundancy network.

It provided recover technology for fault of rapid redundant network, the recovery time <20ms. Product accorded to CE, FCC standard and Industry grade 4 design requirement, support 2 redundant power input and 1 channel relay alarm output, and -40~75℃ working temperature, can meet all kinds of Industrial environment requirement.
