The ABB 3BHE021889R0101 (UFC721BE101) is an ADCVI (Analog to Digital Communication VI) board used in ABB ACS800 series industrial drives.
- High precision analog-to-digital conversion
- Multi protocol communication
- 16 isolated inputs
It is mainly used as the core spare part of ABB ACS1000 driver, responsible for converting analog voltage signals into digital format to achieve precise system control and monitoring.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description.
Main application: Widely used in ABB's medium voltage frequency converters (such as ACS1000 series) and servo drive systems.
Alternative/upgrade suggestion: According to ABB's official technical guidelines, ADCVI boards are currently only available in stock. ABB strongly recommends upgrading it to the CVMI2B upgrade kit for long-term technical support.
Historical models: This board can replace old models such as 3BHB002916R0001 or 3BHB002916R0101.
On the physical level, the board adopts advanced conformal coating to effectively block circuit short circuits or corrosion caused by moisture, salt spray, and conductive dust; On the electrical level, its I/O channels are equipped with high-level electrical isolation and transient voltage suppression (TVS) circuits, which can withstand external electromagnetic interference (EMI) and voltage surges.
At the same time, the onboard chip supports real-time self diagnostic logic, which can monitor power supply voltage and data transmission integrity. Once hardware abnormalities or communication timeouts are detected, the system protection response will be immediately triggered through the fieldbus, fully locking in the control accuracy and overall safety of the variable frequency drive system.
