Features:
- Serves as the field board for SIMOREG units built with disk-type thyristors.
- Pairs two Type D armature ranges with their documented field-current classes.
- Routes the board connection through X102 and four named field terminals.
C98043-A7004-L1 is selected as an electrical configuration, not by the A7004 family name alone.
Its V7/V8 thyristor positions and the eight 0R04 resistors define the field-board circuit arrangement.
The wiring references separate the board-to-board path from the external field conductors used by the converter.
The Siemens C98043-A7004-L1 Field Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Converter Current Pairing
- Converter form: C98043-A7004-L1 is assigned to the Type D arrangement.
- Lower armature class: The 900–1200 A range is paired with a 30 A field.
- Upper armature class: The 1500–2000 A range is paired with a 40 A field.
- Selection boundary: Armature and field values must be checked as one documented pair.
Field-Circuit Hardware
- Thyristor positions: The field circuit identifies devices V7 and V8.
- Resistance set: R1 through R8 are each marked 0R04.
- Board group: The circuit belongs to the A7004-L1/-L2 hardware grouping.
- Configuration check: Device positions and resistor values jointly identify the arrangement.
Connection References
- Internal link: X102 connects with the matching A7002-X102 point.
- Supply terminals: The AC-side field references are 3U1 and 3W1.
- DC field points: Terminals 3D and 3C complete the named field path.
- Lead separation: Betatherm and gating conductors retain their specified cross-sections.
Post-Replacement Control Step
- Required function: P051=22 initiates the internal offset adjustment.
- Trigger condition: The step follows replacement of the C98043-A7004 field board.
- Power state: Hardware work is performed with the converter de-energized.
- Personnel limit: The procedure is reserved for qualified service personnel.
