| EKI-2525/I EKI-2528/I Features 5-port Unmanaged Industrial Ethernet Switch 8-port Unmanaged Industrial Ethernet Switch Provides 5/8 Fast Ethernet ports with Auto MDI/MDI-X Supports 10/100Mbps Auto Negotiation Provides broadcast storm protection Supports 4,000 VDC Ethernet ESD protection Provides surge (EFT) protection 3,000 VDC for power line Provides compact size with DIN-rail/Wallmount, and IP30 metal mechanism Supports redundant 12 ~ 48 VDC power input and P-Fail relay Supports wide operating temperatures from -40 ~ 75 C (EKI-2525I/EKI-2528I) EKI-2525 EKI-2528 RoHS 2002/95/EC COMPLIANT Introduction The EKI-2525/2528 supports a Fast Ethernet solution, and provides a +12 ~ 48 VDC 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. EKI2525/2528 comes with compact metal housing that rates IP30 to help against from dusty industrial environments.
