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 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-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-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.

Carry an SEL-2924 for an always-secure wireless EIA-232 connection.

Avoid exposing personnel to hazardous conditions by enabling them to control and monitor equipment from their trucks or other safe locations.

Instead of unplugging your modem, establish strong access controls with the SEL-3025 and use powerful AES-128/256 and SHA-1/256 to encrypt and authenticate serial links with the Secure SCADA Communications Protocol (SSCP).

The SEL-3031 combines three serial data ports in one radio, allowing up to three different connections and protocols to operate simultaneously. The radio transmits data in the license-free 900 MHz ISM band, providing an economical communications path and backup communications system.

The SEL-3060 is a multipurpose Ethernet radio for distribution automation wireless applications, including SCADA and engineering access.

The SEL-3355 is a versatile computing platform, configurable as a Blueframe application platform or an industrial computer running Windows or Linux operating systems.

The SEL-3360 is a versatile computing platform, configurable as a Blueframe application platform or an industrial computer running Windows or Linux operating systems.

The SEL-3400 is an inexpensive, reliable, and precise way to distribute demodulated IRIG-B time information. With twelve IRIG-B distribution ports and a bright display, the SEL-3400 is ideal for time distribution in panels.

The SEL-3555 RTAC is the most powerful RTAC with unmatched performance and high speed logic capabilities for critical automation, protection, and control schemes. The integrated video port on the RTAC eliminates the need for an additional computer for viewing the HMI. The rugged and reliable design makes it ideal for operating in harsh environmental conditions.

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. 

Adds dial-up access to devices in harsh utility and industrial environments.
