Implement Ethernet network connections with reliable fiber-optic or shielded-twisted-pair (STP) copper cables.

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.

SEL sells wall-mount AC power supplies as accessories for communications and networking equipment. These AC power supplies are commercial temperature rated and appropriate for testing and office environments.

This distribution automation sensor stores load data and monitors the distribution line for loss of current or fault events. Reports are transmitted to an access point on a communications network using an integrated radio.

Apply the SEL-401 for substations with IEC 61850-9-2 sampled values (SV) systems. Sample analog data, such as currents and voltages, then publish those data to a fiber-based Ethernet network for use in other IEDs such as compliant SEL-400-series relays.

The SEL-651RA Recloser Control offers exceptional protection and communications capabilities for Automatic Network Reconfiguration and other distribution automation needs. These capabilities assist you in maintaining reliable service to as many customers as possible in the event of a fault.

The Axion is a fully integrated, modular I/O and control solution suitable for many utility and industrial applications. It combines the communications, built-in security, and IEC 61131 logic engine of the SEL Real-Time Automation Controller (RTAC) product line with a durable suite of I/O modules that provide high-speed, deterministic control performance over an Ethernet network.

The SEL-2488 raises the bar for satellite-synchronized clocks by providing industry-leading accuracy, time distribution, security, and ease of use not offered in other critical infrastructure clocks.

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-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-2740S is designed for the harsh environments commonly found in the energy and utility sectors. The SEL-2740S is the industry’s first SDN-enabled switch. Built for the highest reliability and best performance, it revolutionizes the way networks are engineered and maintained.

Communicate up to 500 meters on multidrop and point-to-point EIA-485 networks.

Communicate up to 4 kilometers on multidrop and point-to-point EIA-485 networks

Connect EIA-232 devices to an EIA-485 network with tough, flexible SEL-2886 EIA-232 to EIA-485 Interface Converter.

The SEL-3390E4 Network Adapter is a PCIe card designed to provide network expansion capabilities for SEL's flexible, robust computer line.

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.
