SEL-2730U
Unmanaged 24-Port Ethernet Switch
The SEL-2730U is an unmanaged 24-port switch, designed for the harsh environments commonly found in the energy and utility industries. The switch supports communications infrastructure built for engineering access, supervisory control and data acquisition (SCADA), and real-time data communications, while offering the same reliability found in SEL protective relays. The SEL-2730U meets or exceeds the IEEE 1613 (Class 1), IEC 61850-3, and IEC 60255 industry standards for vibration, electrical surges, fast transients, extreme temperatures, and electrostatic discharge in communications devices in electrical substations.

Maximized Ethernet Network Robustness
Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2730M Managed 24-Port Ethernet Switch and SEL-2730U meet or exceed IEEE 1613 (Class 1) and IEC 61850-3 standards for communications devices in electric power substations.
Flexible, Modular Design
Upgrade existing sites with 4 Gigabit Ethernet copper ports and 16 10/100 Mbps copper Ethernet ports, built as 4-port modules. Each of the 10/100 Mbps copper port modules can be ordered with single- or multimode fiber-optic ports to meet the unique requirements of your network. In addition, you can add up to 4 fiber-optic Gigabit Ethernet ports via small form-factor pluggable (SFP) transceivers for a total of 24 ports.
Lower Maintenance Needs
Easily integrate the SEL-2730U into an existing network. The SEL-2730U has no settings or configurations to apply. 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.
Reliability in Harsh Environments
Connect to primary and backup power sources simultaneously with dual, hot-swappable power supplies. This ensures that there will not be a loss of service due to a single power source failure. The design minimizes the number of interface points on printed circuit boards (PCBs), resulting in greater reliability. With no fans or other moving parts, the SEL-2730M and SEL-2730U employ the most robust technology available for demanding applications.
