介绍
The EKI-2725/2728 supports Gigabit Ethernet and has a +12 ~ 48 V
DC
冗余电源输入设计，并固定了双重保护机制;电源极性反接
保护和过载电流可恢复式保险丝。前者可保证反向功率导线（如果加号和减号电力电缆被混合设备将不会受到损伤，甚至持续
to operate normally. The later secures the system from overload currents; when the power supply turns normal, EKI-2725/2728 will automatically get back to work. Each port of EKI-
2725/2728 has 2 LED’s to show the link status transmission speed and collision status. It also provides a relay output for an event alarm. In the event of a power failure, the built-in
LED will activate the alarm to notify administrators. Engineers can simply verify the hardware status by checking the LED, and have troubleshooting easy and quick. EKI-2725/2728
comes with compact metal housing that rates IP30 to help against from dusty industrial environments.
