ABB RDCU-02C Drive Control Unit Module Digital Output

The ABB RDCU-02C Drive Control Unit is a compact, coated PLC-style module that serves as the drive-control interface for ABB drive systems (part number 64607901E). It communicates on ABB's PPCS (Power Plate Communication System) bus and provides digital output functionality to external devices, enabling direct signaling from the drive control unit. The RDCU-02C includes an internal 24 VDC supply for digital inputs and a 24 VDC power output (X23) for external I/O, with short-circuit protection described in ABB's RDCU hardware documentation. This module is designed for integration into ABB drive configurations where space is at a premium and a dedicated control unit is required to coordinate signals and status across connected components.
