Category 5e Ethernet Cable

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

ICON Integrated Communications Optical Network

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.

Power Supplies Wall-Mount Power Supplies

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.

SEL-WSO Overhead Wireless Sensor

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.

SEL-401 Protection, Automation, and Control Merging Unit

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.

SEL-651RA Recloser Control

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.

SEL-2240 Axion

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.

SEL-2488 Satellite-Synchronized Network Clock

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.

SEL-2725 Five-Port Ethernet Switch

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.

SEL-2730M Managed 24-Port Ethernet Switch

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.

SEL-2740S Software-Defined Network Switch

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.

SEL-2820 Multimode Fiber-Optic EIA-485 Transceivers

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

SEL-2824 Multimode Fiber-Optic EIA-485 Transceivers

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

SEL-2886 EIA-232 to EIA-485 Interface Converter

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

SEL-3390E4 Network Adapter Card

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

SEL-3620 Ethernet Security Gateway

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 intelligent electronic devices (IEDs).

SEL-5057 SDN Application Suite
The SEL-5057 SDN Application Suite is a collection of software applications that integrate with the SEL-5056 Software-Defined Network Flow Controller to add capabilities to the SEL SDN solution.
