Introduction
The EKI-2525/2528 is a Fast Ethernet solution. Power is a +12 ~ 48 V
DC
redundant input design, and is secured with a double protection mechanism: Power Polarity Reverse Protection
and Overload Current Resetable Fuse. The former tolerates reverse power switching while the later secures the system from overload currents. As the power supply turns normal,
EKI-2525/2528 will automatically get back to work. Each EKI-2525/2528 port 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, which makes troubleshooting quick and easy. EKI-2525/2528 comes with a compact metal IP30 rated housing to protect against dusty industrial environments.
