Project Description

Automation Controller

SEL Programmable Automation Controllers (PACs) are built for utility and industrial applications. They provide rugged and reliable I/O solutions at an economical price. SEL PACs are hardened to meet stringent IEEE and IEC tests for harsh environments, and all are backed by SEL’s no-questions-asked, worldwide, ten-year product warranty.

SEL-2240 Axion

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

SEL-2411 Programmable Automation Controller

The SEL-2411 is a programmable automation controller (PAC) that can be easily customized to fit your needs. Designed to withstand harsh physical and electrical environments, the SEL-2411 is built and tested to meet mission-critical IEEE and IEC protective relay standards.

SEL-3555 Real-Time Automation Controller (RTAC)

The fastest and most powerful Real-Time Automation Controller (RTAC) for advanced data concentration and control.
  • 55 times faster than other RTACs, providing powerful computing for large-scale automation projects.
  • Increases cybersecurity by using exe-GUARD™ whitelist antivirus technology to allow only authorized applications to run.
  • 1 ms deterministic processing intervals for time-sensitive protection and automation control.
  • Eliminates the need for a PC in the substation due to an integrated video port and easy-to-use HMI.

SEL-3505/SEL-3505-3 Real-Time Automation Controllers (RTACs)

Suitable for use in utilities and industrial environments, the SEL-3505/3505-3 Real-Time Automation Controllers (RTACs) are a lower voltage version of the SEL-3530 RTAC. The SEL-3505/3505-3 RTACs are compact and deliver all the standard features of an RTAC, making them excellent options for protocol conversion and secure communication when space is limited.
