The SEL ICON is a wide-area-networking multiplexer optimized for industrial and utility applications. ICON virtual synchronous networking (VSN) preserves the performance characteristics of time-division multiplexing (TDM) when converting to Ethernet as a transport protocol. By combining TDM and Ethernet transport options with a comprehensive range of data interfaces, the ICON makes it easy to migrate legacy network technologies to a converged IT/OT packet-based solution.

The SEL-2725 is an unmanaged five-port switch and copper-to-fiber media converter. Apply to build reliable, safe Ethernet networks in electrical substations, plants, and other mission critical sites.

The SEL-2726U Eight-Port Ethernet Switch is the dependable choice in Ethernet connectivity, whether it’s used in testing stations, laboratories, research and development, manufacturing, or other exacting work areas.

The SEL-2730M is a managed 24-port Layer 2 switch. Apply the switch to build reliable, safe Ethernet networks in electrical substations, plants, and other mission-critical sites. Connect to devices using shielded Category 5/5e/6 copper cables and single- or multimode LC fiber-optic cables.

The SEL-2730U is an unmanaged 24-port Ethernet 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-2741 enables deny-by-default SDN—ideal for Ethernet applications requiring real-time control, measurement, and data acquisition, such as IEC 61850-based communications.

Economically add serial ports to communications processors or computers, and provide secure Ethernet access to serial products.

The SEL-3620 is the ideal substation access point and jump host to help satisfy NERC CIP requirements for securing the electronic security perimeter (ESP). The substation-hardened SEL-3620 secures all Ethernet and serial communications between the enterprise and remote networks, and interoperates with existing business IT and control systems using Internet Protocol Security (IPsec). The SEL-3620 manages passwords for and secures access to relays and IEDs.

The SEL-3622 hosts the same feature set as the SEL-3620 Ethernet Security Gateway in a smaller, low-power form factor and is perfect for cabinets and other low-power locations.
