Advantech's EKI-2525 (5-port) and EKI-2528 (8-port) support a fast Ethernet solution. The power is a 12 VDC to 48 VDC redundant input design and is secured with a double-protection mechanism, power polarity reverse protect and an overload-current resettable fuse. The former tolerates reverse-power wiring while the latter secures the system from overload currents. As the power supply turns normal, EKI-2525 and EKI-2528 will automatically get back to work. Each port of EKI-2525 and EKI-2528 has two LEDs 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 easy and quick troubleshooting. EKI-2525 and EKI-2528 come with compact metal housing that rates IP30 to help against dusty industrial environments.
