Features:
- ABB identifies SDCS-FEX-2A article 3ADT311500R1 as an internal field-exciter board for specified DCS converter module sizes. It uses a half-controlled single-phase bridge and provides the documented field-current ranges.
- Confirm article number, receiving converter type C1/C2/A5, single-phase input class, required field-current range, X1 wiring and control-board interface.
- Use it only in the DCS field circuit and converter size listed by the ABB technical data.
SDCS-FEX-2A 3ADT311500R1 is selected from the complete manufacturer identity and receiving-system evidence. Isolate armature and field supplies, prove discharge, label X1 and control-board connections, and inspect field insulation before fitting. Check field continuity and polarity, then monitor field-current build-up, regulator response and protection diagnostics during controlled startup.

Important Notice: Confirm the complete model, article number and installed configuration before replacement. All links open in a new page.
ABB places the board in specified C1, C2 and A5 converter modules; the cabinet configuration must agree.
Use the correct 0.3–8 A or 0.3–16 A range for the receiving armature-current class.
Verify field resistance, polarity, current build-up and regulator diagnostics before motor loading.
