Siemens 6RY1703-0EA02 Field-Supply / Excitation Board
A SIMOREG DC MASTER field-supply assembly identified by the full 6RY MLFB and its associated board record.
Product Identification
Siemens 6RY1703-0EA02 is a field-supply or excitation-board spare for the SIMOREG DC MASTER platform. Service references associate the MLFB with board identity C98043-A7004-L2.
This assembly belongs to the motor-field power path. Exact suitability depends on the host converter, field-current requirement, board execution and connector arrangement rather than on the 6RY1703 prefix alone.
Published information for this legacy spare is limited; the page therefore keeps converter ratings and optional configurations outside the record unless they are shown on the installed Siemens documentation.

Functions
Field-power control path
Supports the excitation supply assigned to the connected DC motor field circuit.
Board-level identity
The C98043 board marking provides a second traceability point alongside the 6RY catalog number.
Converter integration
Operation is coordinated with the SIMOREG control and protection configuration.
Maintenance continuity
Exact records reduce the risk of fitting a visually similar but electrically different 6RY assembly.

FAQ
Q01
What second identity is associated with 6RY1703-0EA02?
+
Service records associate the MLFB with Siemens board code C98043-A7004-L2; both markings should be captured.
Q02
Can a nearby 6RY1703 catalog number replace 6RY1703-0EA02?
+
Not by family resemblance. Board function, suffix, revision, connector map and host converter must all agree.
Q03
Which motor information matters for a 6RY1703-0EA02 enquiry?
+
Provide armature and field nameplate data, required field current and voltage, motor connection drawing and the host SIMOREG MLFB.
Q04
What should be recorded before disconnecting 6RY1703-0EA02?
+
Capture every plug and conductor, parameter backup, field-circuit protection, board revision and the active fault history.
Q05
How is a replacement 6RY1703-0EA02 field path accepted?
+
Verify insulation and continuity under the approved procedure, controlled field-current build-up, stable regulation and correct protection response.
