RDCU-02C 64607901 ABB Relion® 650/670 series protection devices distributed communication control units
ABB RDCU-02C is a Distributed communication and control unit (Remote Distributed) specifically designed for Relion® 650 and 670 series multi-functional protection relays (such as REF650, REM650, REB650, RED670, etc.) (Communication Unit). As an intelligent expansion node of the main protection device, RDCU-02C not only provides additional digital input/output (DI/DO) channels, but also supports IEC 61850 GOOSE communication, achieving high-speed interlocking, state sharing and distributed automation logic.
