Features:
- ABB article HIEE451116R0001 identifies FM9925A-E as a communication interface board.
- System role: provides the documented controller communication interface.
- Compatibility requires the documented hardware execution, connectors, position and project configuration.
HIEE451116R0001 FM9925A-E must remain matched to ABB UNITROL excitation systems. Isolate the excitation cabinet, label every connector and preserve the documented board position and grounding. Verify board diagnostics, excitation permissives, mapped signals and protection interlocks before returning the unit to automatic control.
Official source boundary: ABB technical documentation for FM9925A-E. Unverified nearby-model values are withheld.
