SEL-2725
Five-Port Ethernet Switch
The SEL-2725 is an unmanaged five-port switch and copper-to-fiber-optic media converter. Apply to build reliable, safe Ethernet networks in electrical substations, plants, and other mission-critical sites. Connect to devices in the same cabinet using shielded twisted-pair Category 5 cable, and communicate with the substation or plant local-area network (LAN) with a fiber-optic link.
Starting At
$470 USDFlexible Network Expansion—Apply as an unmanaged “no-settings” switch/media converter. LED indicators simplify commissioning and solve network problems. Convert Ethernet links to fiber-optic Ethernet link(s). Ports 1-4 automatically configure for crossover cables, speed, and half- or full-duplex operation.
Stability in Tough Environments—Install in harsh environments. The SEL-2725 withstands vibration, electrical surges, electrostatic discharge, fast transients, and extreme temperatures. It meets or exceeds IEEE 1613 and IEC 61850-3 standards for communications networking devices in electric power substations.
System Reliability—Compare SEL's superior specification compliance, lower price, and worldwide, ten-year warranty to alternatives. Directly power the SEL-2725 from 12 Vdc, 24/48 Vdc, or 125/250 Vdc or 110/240 Vac sources; the SEL-2725 power supply mean time between failures (MTBF) exceeds 3,000 years.
Environmental-Conditioning Specifications—Temperature range of –40° to +85°C (–40° to +185°F); good for critical utility and industrial environments.

Details
Tough
Withstands vibration, electrical surges, electrostatic discharge, fast transients, and extreme temperatures. Meets or exceeds IEEE 1613 (class 2) and IEC 61850-3 standards for communications networking devices in electric power substations. The SEL-2725 drops no packets throughout this rigorous testing.
Reliable
Depend on reliability from SEL. Compare our superior specification compliance, lower price, and worldwide, ten-year warranty to alternatives. Directly power the SEL-2725 from 24/48 Vdc or 125/250 Vdc or Vac sources; observed power supply MTBF exceeds 3,000 years.
Simple
Easily apply unmanaged “no-settings” switch/media converter. Just connect power, Ethernet devices, and the fiber-optic Ethernet network. LED indicators simplify commissioning and solving network problems. Copper Ethernet ports automatically configure for crossover cables, speed, and half- or full-duplex operation.
Safe
Convert Ethernet links to fiber-optic Ethernet links. Use fiber-optic Ethernet links outside of cabinets for increased safety and electrical noise immunity.
Dependable unmanaged Ethernet LAN connectivity in harsh environments, such as substation and industrial facilities. Supports 1 fiber and 4 copper 10/100 Ethernet ports.
Dependable unmanaged Ethernet LAN connectivity in harsh environments, such as substation and industrial facilities. Supports 2 fiber and 3 copper 10/100 Ethernet ports.
The Firmware IDs for older versions of the firmware can typically be found in Appendix A of the instruction manual.
