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.
What old models can this 3BHE021887R0101 UBC717 BE101 module replace?
This board is a direct upgrade replacement for EE300927R0101 (and related sub models such as HIE300927R0001/0101), ensuring compatibility with existing systems.
What ABB systems is the 3BHE021887R0101 UBC717 BE101 mainly used for?
Mainly used as spare parts for the ACS 1000 frequency converter series, it is also widely applied in 800xA distributed control systems (DCS) and various industrial and marine automation controls.
What are the safety precautions during installation and operation?
Strictly prohibit live operation: This option board does not support hot swapping, and all power voltages must be cut off before insertion or removal to prevent unforeseen damage. Anti static protection: The module is sensitive to static electricity, and it is necessary to wear an anti-static wristband or use an anti-static floor mat during operation.
What role does this board play in the ACS 1000 frequency converter?
It usually serves as the interface control layer, responsible for collecting external operation instructions (such as start, stop, emergency stop signals) and providing feedback on the operating status of the frequency converter (such as fault alarms, operating frequency arrival, etc.). It is the
Do I need to reprogram after replacing the new 3BHE021887R0101 UBC717 BE101 board?
Normally, there is no need to program the board itself. This module is a standard I/O expansion unit, and its logic is determined by the main controller (such as AC800M). As long as the hardware version (Revision) of the new board is consistent with the old version, simply replace it and ensure that the dip switch (if any) is set correctly to resume operation.
