Introduction
The EKI-2525/2528 supports a Fast Ethernet solution, and provides a +12 ~ 48 V
DC
redundant power 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 (devices will not be damaged if the plus and minus power cables are mixed, even
continuing to operate normally. The later secures the system from overload currents; when the power supply turns normal, EKI-2525/2528 will automatically get back to work. Each
port of EKI-2525/2528 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-
2525/2528 comes with compact metal housing that rates IP30 to help against from dusty industrial environments.
