+86 18150117685Coated external DC voltage measurement resistor board for DCS880 DC Drives
This coated resistor board provides an external motor-armature voltage measurement path for documented DCS880 H1 through H5 configurations where the internal measurement cannot see motor voltage across an open DC breaker or US-style DC contactor.
The board is installed outside the drive module, connects the positive and negative motor DC potentials to X1 and X2, and sends the scaled voltage from X3 to analog input AI3; the photographed PCB is labeled SDCS-UCM-1C.
Ordering note: Verify the complete model, installed system, revision and current manufacturer documentation before purchase or installation.
| Manufacturer / drive family | ABB DCS880 |
|---|---|
| Product ID | 3ADT220090R0008 |
| ABB type designation | SDCS-UCM-1-COAT |
| PCB label | SDCS-UCM-1C |
| Board function | External DC voltage measurement resistor board |
| Installation | Outside DCS880 module, sizes H1–H5 |
| Connections | X1 positive DC, X2 negative DC, X3 scaled output to AI3 |
| Voltage setup | X1/X2 position 4/4 to 500 VDC; 3/3 to 600 VDC |
Compatibility depends on the complete ordering code, installed hardware, wiring and approved engineering data.
External mounting allows the board to measure the motor-side DC voltage when a breaker or US-style contactor is open.
Positive motor DC connects to X1 and negative motor DC connects to X2.
The reduced-voltage signal from X3 connects to analog input AI3 on the drive.
Positions 4 and 4 apply through 500 VDC, while positions 3 and 3 apply through 600 VDC.
Power must be isolated and the motor DC potential at X1 and X2 must be verified safe before work begins.
Send the complete SDCS-UCM-1-COAT 3ADT220090R0008 model, quantity, installed system, destination and clear label photos. Availability and condition will be confirmed before quotation.
