The RDCU-02C ASXR7220 is a drive control unit module within the ACS800 series frequency inverter platform. The hardware contains a printed circuit board with a conformal coating treatment, denoted by the suffix C, to prevent damage from environmental moisture and chemical contamination.
250 mA base current consumption
IP00 bare board protection rating
ASXR7220 application firmware designation
The board requires an external 24 V DC power input and configures multiple onboard communication interfaces, including digital/analog I/O channels and dedicated DDCS optical fiber links. Its baseline I/O configuration includes 3 analog inputs, 2 analog outputs, 7 digital inputs, and 3 relay outputs. This unit is housed internally within the drive frame or a separate control box utilizing plastic spacer supports, carrying an IP00 hardware classification.
The RDCU-02C ASXR7220 ABB Interconnect Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
