Introduction
The EKI-2528D/DI is DNV certificate product supports 8-port Fast Ethernet solution. The power is a +12 ~ 48 V
DC
redundant input design, and is secured with a double protection
mechanism: Power Polarity Reverse Protect and an Overload Current Fuse. The former tolerates reverse power wiring while the later secures the system from overload currents. Each
port of EKI-2528D/DI has 2 LED’s to show the link status transmission speed. 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-2528D/DI comes with
compact metal housing that rates IP30 to help against from dusty industrial environments.
