Features:
- The complete legacy identity combines ABB article HIEE300931R0001 with board designation PPC381 AE. Public ABB family documentation does not validate generic 24 V, IP or temperature values for this exact board.
- Match both printed codes, PCB revision, fitted programmable devices, connector population, firmware/configuration and the receiving UNITROL cabinet drawing.
- Use it only in the excitation-control position documented for PPC381 AE in the installed generator system.
HIEE300931R0001 PPC381 AE is selected from the complete manufacturer identity and receiving-system evidence. Back up configuration, photograph connectors and jumpers, isolate excitation power and follow ESD handling requirements. Verify board supplies and diagnostics first, then prove sensing polarity, regulator response, limiters, alarms and field-current control under the plant procedure.
Official source: Complete ABB board marking supported by applicable UNITROL system documentation. The public source supports the excitation-system context; exact board ratings remain nameplate and project-document controlled.
HIEE300931R0001 PPC381 AE official technical documentation and verified Moore Automated resources.
Important Notice: Confirm the complete model, article number and installed configuration before replacement. All links open in a new page.
Use HIEE300931R0001 and PPC381 AE together with the PCB revision and fitted-device labels.
Confirm voltage sensing, current compensation, field-command and limiter connections from the machine schematic.
After configuration recovery, prove polarity, voltage regulation, limiters and alarms under controlled conditions.
