Product Overview

ABB RDCU-02C is a separately mounted drive control unit documented for ACS800 cabinet installations and inverter-module configurations. It incorporates the RMIO-02C motor control and I/O board, providing basic analog, digital and relay interfaces together with slots for optional I/O and communication modules. The unit is typically mounted vertically on a cabinet rail near the inverter module and connects to the power stage through optical-fiber links. Procurement and replacement work should verify the complete RDCU designation, the RMIO board label, application-program identification, optional module population, control-panel connection, terminal layout and optical-link arrangement for the installed drive.

Lifecycle Note

The reviewed ABB hardware manuals identify RDCU-02C and its RMIO-02C configuration but do not state a current lifecycle designation for the exact control unit. No lifecycle status is inferred. Replacement planning should instead verify the label, software type and code, option modules, I/O wiring and optical connections.
