Automation Controllers
Simplify Automation With SEL Real-Time Automation Control
Making the transition to complete system automation requires controllers that are flexible enough to integrate with your existing devices, durable enough to meet the most rigorous physical demands, and powerful enough to deliver the highest performance possible.
That’s why we created our family of SEL Real-Time Automation Controllers (RTACs), designed to reduce operating costs and increase productivity in your system without compromising reliability.
SEL RTACs can increase the security of your communications to remote intelligent electronic devices (IEDs) and are essential components in your wide-area control and monitoring schemes. With an RTAC, you can find and correct problems at faster speeds from a remote location, saving time and money. RTACs can also act as data concentrators in your distribution automation applications by seamlessly communicating with and incorporating new and legacy devices. In addition, depending on the model, the integrated I/O provides even more opportunities for expansion in other applications, such as industrial process control and retrofit control for remote apparatus. With our long history of dedication to security, each RTAC has industry-leading physical and cybersecurity features built into its core.
Supervisory Control and Data Acquisition (SCADA)
As a central controller, the SEL-3555 Real-Time Automation Controller (RTAC) can communicate between substations, regulating and managing data for the entire system. The built-in video port brings high-quality control, annunciation, and alarm management via the integrated web HMI. With its advanced processing power, the SEL-3555 is ideal for many demanding applications, such as high-speed automation, synchrophasor processing, and distribution automation as well as integrating data from multiple substations.
Power System Automation
SEL-3530/3530-4 RTACs allow you to use the abilities of other devices, giving you a high-performance control and monitoring scheme. By bridging the connection between Mirrored Bits communications and IEC 61850 Generic Object-Oriented Substation Event (GOOSE) networks, these efficient automation controllers provide secure and reliable communications.
Substation RTU
SEL Axion’s versatility as an RTU allows you to gather digital and analog signals from remote locations. Then, with its variety of industry-standard protocols, you can distribute the data to a central SCADA system or HMI, providing efficient system-wide visibility.
Remote Engineering Access and SCADA Communications

SEL-3505/3505-3 RTAC’s compact size is perfect for small enclosure cabinets. Placing an RTAC in these cabinets can provide continuous monitoring and intrusion detection. Collect, measure, and organize data from both serial and Ethernet IEDs through several of the RTAC’s standard protocols, such as Modbus, DNP3, and M irrored Bits communications.
RTAC HMI
Integrated Visualization and Control The RTAC HMI allows you to visualize your substation electrical power system and includes the benefits of traditional SCADA and HMI packages.
System Components
SEL-3555 RTAC
The SEL-3355 is the fastest and most powerful RTAC for advanced data concentration and control. The SEL-3555 provides a powerful solution for data management, either in the substation or at a central location. Manage and archive system data, view real-time information, and control substation equipment. Use the built-in video port to integrate an HMI for control, annunciation, and alarm management. The SEL-3555 provides the flexibility, reliability, and power to meet your most demanding substation automation projects.
SEL-3530/3530-4 RTACs
The SEL-3530/3530-4 RTACS are powerful, reliable, and secure multifunction controllers. The SEL-3530/3530-4 RTACs provide complete and flexible system control with integrated security, seamless configuration, unified logic, reliability, and a variety of different form factors and I/O and communications port options.
SEL-3505/3505-3 RTACs
The SEL-3505/3505-3 RTACs offer economical multifunctional control in a compact package. The SEL-3505/3505-3 RTACs are lower-voltage versions of the SEL-3530 and deliver all the standard features of an RTAC in a compact package, making them excellent options for protocol conversion and secure communication when space is limited.
SEL-2240 Axion
The SEL-2240 Axion provides dependable control for harsh environments in a fully integrated, flexible platform. The Axion is a fully integrated, modular I/O and control solution ideally suited for utility and industrial applications. It combines the communications, built-in security, and IEC 61131-3 logic engine of the SEL RTAC family with a durable suite of I/O modules that provide high-speed, deterministic control performance over an EtherCAT network.
