Information

Overview Manuals Common Applications Control Functions

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).

Metallurgical Steel Rolling

Operates within hot or cold rolling main drive inverters to receive speed reference signals and calculate motor torque outputs.

Paper Industry

Deployed in paper machine multi-motor sectional drive systems to execute synchronous speed control across roller sections using tension sensors.

Mine Hoists

Controls heavy-duty AC motors of mine hoists, managing heavy-load startup and braking logic coordinated with mechanical brakes.

Oil and Gas Drilling

Controls AC/DC variable frequency operations of rig mud pumps, drawworks, and top drive systems, utilizing the coated circuit board to withstand field salt spray environments.

Power and Boiler Fans

Controls the variable frequency speed regulation of boiler induced and forced draft fans in power plants, transmitting operating parameters to the DCS via fieldbus cards.

Rubber and Plastics Compounding

Controls main motors of large internal mixers and extruders, monitoring current and torque feedback to prevent overload mechanical damage.

The RDCU-02C ASXR7220 manages drive control, signal processing, communication, and parameter handling within the ACS800 drive system. It interfaces with power modules, control panels, I/O circuits, and optional communication boards to support drive operation, monitoring, and maintenance.

Technical notes

The ASXR7220 designation identifies the specific system application firmware package version compatible with the underlying hardware processor. Through the onboard optical fiber ports, the module establishes direct communication with power units, upper automation controllers, or peripheral fieldbus adapter modules.
