SDCS-UCM-1C 3ADT220090R0008 is used to identify an external voltage-measurement board configuration associated with the SDCS-UCM-1 function.
The documented arrangement reduces motor armature DC voltage through two resistor chains before the signal reaches the drive analog input.
Confirm the complete board identity, DCS880 frame, tap selection, polarity, wiring, insulation, and safety procedure before service.
Availability, condition, price, and shipping time for SDCS-UCM-1C 3ADT220090R0008 are confirmed during quotation.

- X1 connects to the positive motor armature terminal C1
- X2 connects to the negative motor armature terminal D1
- X3 carries the reduced-voltage signal to XAI:AI3
- Select both resistor-chain tap positions from the ABB motor-voltage table
- Use identical X1 and X2 positions for the documented voltage ranges
- Verify the actual motor voltage before changing either tap position
- X1 and X2 are at motor DC potential
- Installation and measurement work is restricted to qualified personnel
- Isolation and absence of dangerous voltage must be verified before service
- External motor-armature DC voltage measurement for documented DCS880 H1...H5 installations
- Drive configurations requiring a reduced signal at analog input XAI:AI3
