Description
The controller collects data from protection terminals, converts protocols and runs IEC 61131 logic. A built-in web HMI is output through a video port, so a separate operator computer is not required. The compact SEL-3505 is designed for small substations, DG sites and reclosers, and is powered from 12 V or 24/48 V DC. In the SCADA system, the RTAC acts as a data concentrator between terminals and the dispatch center.
