SEL SEL-2730U Unmanaged 24-Port Ethernet Switch



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.

Tough

The SEL-2730U withstands vibration, electrical surges, electrostatic discharge, fast transients, and extreme temperatures.

It meets or exceeds IEEE 1613 (Class 1) and IEC 61850-3 standards for communications networking devices in electric power substations. The SEL-2730U drops no packets throughout this rigorous testing.

Reliable Depend on reliability from SEL. Compare its superior specification compliance, lower price, and worldwide, ten-year product warranty to other industrial switches.

Directly power the SEL-2730U from 24/48 Vdc or 125/250 Vdc or Vac; the observed power supply mean time between failures (MTBF) exceeds 2.000 years.*

Simple Easily apply the unmanaged “no-settings” switch. 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.

Flexible The base model SEL-2730U has 4 copper Gigabit Ethernet ports and 16 copper 10/100 Mbps Ethernet ports, built as 4-port modules.

Each of the 10/100 Mbps copper port modules can be ordered as single- or multimode fiber-optic ports to meet the unique requirements of your network. In addition, up to 4 fiber-optic Gigabit Ethernet ports may be added via SFP transceivers, for a total of 24 ports.

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.
