The ABB 3BHE021887R0101 (UB C717 BE101) is an OVVP digital input/output (DIO) board designed specifically for transmission systems such as ACS 1000 frequency converters. This module adopts a coated process, which can effectively resist corrosion and is suitable for harsh industrial environments such as offshore platforms, chemical treatment, and water treatment.
- OVVP-Board Coated
- ACS1000
- Typically 200 mA
In ABB's transmission architecture, UBC717 BE101 plays the role of a "critical bridge" between the frequency converter control layer and the on-site execution layer. It is not only responsible for collecting emergency stop, travel limit, and operator commands, but also drives external contactors and status indicator lights through relay or transistor outputs.

ACS 1000 medium voltage frequency converter: As a key spare part, responsible for handling the logical signal exchange between the frequency converter and the external control cabinet.
800xA control system: integrated into the DCS distributed control system, connecting on-site devices such as limit switches, proximity sensors, and motor starters.
Industrial machinery drive: control circuits for compressors, blowers, cooling tower motors, and lifting machinery.
On the physical level, the board is constructed with a robust chemical barrier through advanced conformal coating, effectively blocking circuit corrosion and short circuit risks caused by moisture, salt spray, and conductive dust; On the electrical level, the core processing unit and peripheral I/O interfaces are equipped with high-level electrical isolation and transient voltage suppression (TVS) circuits, which can resist strong electromagnetic interference (EMI) and external voltage surges.
At the same time, the onboard chip is equipped with real-time monitoring self diagnostic logic and hardware watchdog. Once a voltage drop or program abnormality is detected, it will immediately trigger a safety interlock response, fully locking the data integrity of the core control logic and the safety of system operation.
