Siemens 6RY1803-0CA11 2Q Field Supply Board
An active Siemens spare field-supply board identified by both its 6RY ordering number and C98043 board reference.
Product Profile
6RY1803-0CA11 is a Siemens spare part described as a two-quadrant field supply board. The Siemens product record associates it with board reference C98043-A7115-L21.
Both identifiers should be captured because installed boards may show the C98043 reference more prominently than the 6RY order number. Host converter identity and field-circuit data remain necessary for a controlled exchange.

System Role
Controls the matched two-quadrant field-supply function in the host Siemens drive.
Provides a dual identity through 6RY1803-0CA11 and C98043-A7115-L21 markings.
Supports active spare-parts procurement with the exact board reference retained.
Keeps field-circuit commissioning tied to the installed converter and motor data.
Compatibility
- Match both the 6RY order number and C98043 board reference.
- Record the complete host converter MLFB, serial number and board position.
- Preserve field winding, supply, fuse, contactor and connector details.
- Do not substitute a similar 6RY1803 board without a documented Siemens relationship.
Applications
- Field-supply repair in the documented Siemens DC drive or converter.
- Like-for-like replacement where C98043-A7115-L21 is visible on the installed board.
- Spares management that retains both ordering and board-reference identities.
FAQ
Why are two identifiers recorded for 6RY1803-0CA11?
Siemens lists the spare order number together with board reference C98043-A7115-L21, and either may be the clearest installed marking.
What host data should accompany 6RY1803-0CA11?
Provide the complete converter MLFB, serial number, field-circuit ratings, board position and connector photographs.
Can another 6RY1803 field board replace 6RY1803-0CA11?
Only when Siemens documentation confirms the relationship for the exact host converter and field-supply execution.
What should be checked before energizing 6RY1803-0CA11?
Verify field wiring, fuses, contactors, grounding, connector seating, isolation and the approved drive configuration.
What proves the 6RY1803-0CA11 repair is complete?
Record stable diagnostics, controlled field-current response, motor behavior, interlocks and the final drive test.
