ABB UF C721 BE101 3BHE021889R0101 ADCVI-Board Coated | ACS1000

ABB UF C721 BE101 ADCVI-Board Coated - ACS1000 Drive Control Solution

The ABB UF C721 BE101 (3BHE021889R0101) represents a critical control board component engineered for ACS1000 series medium voltage drives. This conformal-coated ADCVI (Analog-to-Digital Converter and Voltage Interface) board provides essential signal conditioning, voltage monitoring, and control interface functions for industrial drive systems operating in demanding environments requiring enhanced protection against moisture, dust, and chemical contaminants.

Technical Specifications

Product Evolution & Upgrade Path

Legacy Compatibility: The UF C721 BE101 replaces earlier ADCVI board versions including 3BHB002916R0001, HB002916R0001, 3BHB002916R0101, and HB002916R0101, providing backward compatibility for existing ACS1000 installations while incorporating design improvements for enhanced reliability.

Upgrade to CVMI2B Technology: ABB recommends upgrading all ACS1000 drives with CVMI2B-board upgrade kits for improved performance and extended lifecycle support. The replacement product 3BHE037864R0101 represents the next-generation CVMI2B technology offering enhanced diagnostic capabilities and reduced maintenance requirements.

First-Time CVMI2B Upgrade Requirements: When replacing ADCVI with CVMI2B boards for the first time in ACS1000 systems, one of the following upgrade kits must be ordered based on drive variant:

• ACS1000A: Kit 3BHB040806R0001 (Air-cooled variant)
• ACS1000W: Kit 3BHB040806R0002 (Water-cooled variant)
• ACS1000i: Kit 3BHB040806R0003 (Industrial variant)

Each upgrade kit includes comprehensive installation documentation, configuration guidelines, and commissioning procedures to ensure successful migration.

Functional Overview

The ADCVI-Board serves as the critical interface between the drive's power electronics and digital control system, performing multiple essential functions:

Analog Signal Conditioning: Processes voltage and current feedback signals from the drive's power stage, applying precision filtering and scaling to ensure accurate representation of electrical parameters for the control algorithms.

High-Resolution A/D Conversion: Converts conditioned analog signals into digital format with sufficient resolution and sampling rate to support advanced control strategies including vector control, direct torque control, and active front-end rectification.

Voltage Monitoring: Continuously monitors DC bus voltage, AC line voltages, and auxiliary power supply levels, providing real-time data for protection functions and performance optimization.

Conformal Coating Protection: The specialized coating provides moisture resistance, chemical protection, and enhanced insulation properties, making this board suitable for installation in environments with high humidity, corrosive atmospheres, or airborne contaminants common in mining, marine, and heavy industrial applications.

Industrial Application Environments

Mining & Minerals Processing: Controls large conveyor systems, crushers, and grinding mills in underground and surface mining operations where dust, moisture, and vibration challenge electronic reliability.

Marine & Offshore: Drives propulsion motors, deck machinery, and auxiliary systems on vessels and offshore platforms exposed to salt spray, humidity, and temperature cycling.

Pulp & Paper Mills: Manages paper machine drives, winders, and material handling systems in high-humidity environments with chemical exposure from bleaching and coating processes.

Steel & Metals: Powers rolling mills, continuous casters, and material handling equipment in steel plants with extreme temperatures, scale, and electromagnetic interference.

Water & Wastewater: Controls large pumps and blowers in treatment facilities where moisture, corrosive gases, and outdoor installation require enhanced environmental protection.

Installation & Maintenance Considerations

MV A Supportline Approval: This product requires ABB MV A Supportline approval for availability verification and application suitability assessment. Contact ABB technical support or authorized distributors to confirm compatibility with your specific drive configuration and firmware version.

Handling Precautions: The conformal coating provides environmental protection but requires careful handling during installation. Avoid mechanical stress on board edges, connector areas, and component leads. Use ESD-safe procedures when handling and installing the board.

Replacement Procedure: Board replacement should be performed by qualified technicians following ABB service procedures. Ensure drive is fully de-energized and locked out, verify DC bus discharge, and follow proper grounding protocols before accessing control electronics.

Configuration Transfer: When replacing ADCVI boards, configuration parameters may need to be re-entered or transferred from backup files. Consult drive documentation for parameter backup and restoration procedures specific to your drive firmware version.

Quality Assurance & Availability

Manufactured in ABB's Swiss facility under ISO 9001 quality management systems, each UF C721 BE101 board undergoes functional testing including A/D conversion accuracy verification, signal conditioning linearity checks, and environmental stress screening. The board is stocked at multiple ABB distribution centers globally including Finland (FIPSEEXPU), Singapore (SGRDC002EXPU), China (CNIAB001EXPU), India (SGIND002EXPU), and Australia (AUABB024EXPU) for rapid delivery to support emergency replacements and planned maintenance activities.
