More Information

Overview Manuals Wiring Taps Safety Application
  • External DC voltage measurement-board identity for applicable DCS880 hardware
  • Official base-board function is documented for DCS880 frame sizes H1 through H5
  • Complete board designation and ABB article number must be matched together
ABB 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.

Description
ABB SDCS-UCM-1C 3ADT220090R0008 is an external DC voltage measurement-board identity associated with the documented SDCS-UCM-1 function for DCS880 drives.

ABB specifies the base board for DCS880 frame sizes H1 through H5, mounted outside the drive module, with two resistor chains connected across the motor armature DC voltage.

Before installation or replacement, verify both identifiers, frame size, X1/X2 tap selection, C1/D1 polarity, X3 connection to XAI:AI3, insulation, routing, and the ABB safety procedure.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Where is ABB SDCS-UCM-1C 3ADT220090R0008 installed in a DCS880 system?
ABB documents the SDCS-UCM-1 base measurement board outside the DCS880 module for the applicable H1 through H5 installation.
How are the positive and negative DC connections made for ABB SDCS-UCM-1C 3ADT220090R0008?
The ABB instructions connect X1 to positive motor terminal C1 and X2 to negative motor terminal D1. Use the exact manual and observe all high-voltage safety procedures.
How is the reduced measurement signal connected from ABB SDCS-UCM-1C 3ADT220090R0008?
ABB routes the reduced-voltage signal through X3 to analog input AI3 at XAI:AI3 on the drive control hardware.
How should the X1 and X2 taps be selected for ABB SDCS-UCM-1C 3ADT220090R0008?
Select both tap positions from the ABB nominal motor-voltage table for the installed DCS880 system; do not choose positions by visual similarity.
Are the X1 and X2 terminals on ABB SDCS-UCM-1C 3ADT220090R0008 safe extra-low-voltage points?
No. ABB warns that X1 and X2 are at motor DC potential. Qualified personnel must isolate, verify de-energization, and follow the drive safety instructions.
Can the DCS880 internal voltage measurement remain in use with the external SDCS-UCM-1 board?
ABB states that the internal voltage measurement remains connected and usable when the documented external measurement arrangement is installed.
What should be provided when requesting ABB SDCS-UCM-1C 3ADT220090R0008?
Provide both identifiers, DCS880 type and frame size, board and connector photos, existing tap positions, required condition and quantity, and destination.
