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.
Flexible 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.

Power indicator
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.
