EKI-2725 EKI-2728 5-port Gigabit Unmanaged Industrial Ethernet Switch 8-port Gigabit Unmanaged Industrial Ethernet Switch Features NEW Provides 5 or 8 Gigabit Ethernet ports with Auto MDI/MDI-X Supports 10/100/1000Mbps Auto Negotiation Supports jumbo frame transmission up to 9kbytes Supports 4,000 VDC Ethernet ESD protection Provides surge (EFT) protection 3,000 VDC for power line Provides Slim size, DIN-rail with IP30 metal mechanism Supports Redundant 12 ~ 48 VDC power input and P-Fail Relay Provides broadcast storm protection EKI-2725 EKI-2728 RoHS COMPLIANT 2002/95/EC Introduction The EKI-2725/2728 supports Gigabit Ethernet and has 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-2725/2728 will automatically get back to work. Each port of EKI2725/2728 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-2725/2728 comes with compact metal housing that rates IP30 to help against from dusty industrial environments.
