Advantech EKI-2728 8-Port Unmanaged GBE Ethernet

The EKI-2728 supports Gigabit Ethernet. The power is a +12V ~ 48VDC redundant input design, and is secured with a double protection mechanism: Power Polarity Reverse Protect and an Overload Current Resetable Fuse. The former tolerates reverse power wiring while the later secures the system from overload currents. As the power supply turns normal, EKI-2728 will automatically get back to normal operation state.
