5-port Unmanaged Industrial Ethernet EKI-2525/I Switch 8-port Unmanaged Industrial Ethernet EKI-2528/I Switch Features Provides 5/8 Fast Ethernet ports with Auto MDI/MDI-X Supports 10/100 Mbps Auto-Negotiation Provides compact size with DIN-rail/Wall mount, and IP30 metal mechanism Supports redundant 12 ~ 48 V power input and P-Fail relay DC Supports wide operating temperatures from -40 to 75 C (EKI-2525I/EKI-2528I) EKI-2525 EKI-2528 Introduction The EKI-2525/2528 is a Fast Ethernet solution. Power is a +12 ~ 48 V redundant input design, and is secured with a double protection mechanism: Power Polarity Reverse Protection DC 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 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, which makes troubleshooting quick and easy. EKI-2525/2528 comes with a compact metal IP30 rated housing to protect against dusty industrial environments.
