SEL Real-Time Automation Controllers (RTACs) provide automation and data management in the substation. They manage and archive system data, allow viewing of real-time information, and control substation equipment. Additionally, SEL RTACs allow you to integrate an HMI for control, annunciation, and alarm management.
