ABB identifies 3BHE022293R0101 as PC D232 A: PEC80-CIO, a combined input/output board in the UNITROL 6000 family. The board belongs to the excitation-system control hardware and must be matched by complete article number, PC D232 A designation, installed controller arrangement and visible board revision before replacement.
3BHE022293R0101 PCD232A is selected by the complete ABB article number, PC D232 A designation and installed UNITROL hardware arrangement. Record the board revision and every connected plug before service.
Important Notice: Confirm the complete model, revision and installed system before replacement.
ABB lists PC D232 A as a CIO combined input/output board. Use it only in the documented UNITROL 6000 controller position whose connectors and board revision match the removed item.
Before replacement, record the controller or panel identity, slot, connected plugs and cable labels. Verify the restored hardware against the applicable ABB service documentation before energizing the excitation system.
Do not select a neighboring PCD designation from appearance. Match 3BHE022293R0101, PC D232 A, visible revision and interface arrangement, then complete the required input/output functional checks.
Engineering check: Confirm 3BHE022293R0101 PCD232A is the PC D232 A: PEC80-CIO board assigned to the installed UNITROL 6000 controller. Compare board revision, rack position, connector coding and configured combined-I/O channel map before replacement.
Acceptance test: Exercise every used input and output from the field terminal to the controller database. Verify polarity, scaling, isolation and alarm state, then confirm no channel is cross-mapped after a controlled controller restart.
