System Role and Capabilities

The D20ME acts as the central intelligence of a substation automation system. It collects data from field devices, processes logic and control commands, and communicates with higher-level SCADA or energy management systems. Its architecture supports deterministic behavior, which is essential for protection, control, and operational visibility.

This unit is especially valued in projects where reliability and backward compatibility are critical.
