ABB 3BSE004940R0001 SDCS-PIN-51

ABB 3BSE004940R0001 – SDCS-PIN-51 is a Power Interface / Measurement Card used in ABB DC drive systems, especially the DCS500/DCS600/DCS800 series thyristor converters.

Product Information

• Manufacturer: ABB
• Part Number: 3BSE004940R0001
• Type Designation: SDCS-PIN-51
• Product Name: SDCS-PIN 51 Measurement Card
• Function: Power interface and measurement board
• Application: ABB DC drive power converters
• Replacement / successor references:
  • Replaced by 3ADT220090R0006 (SDCS-PIN-51-COAT) in some ABB spare-part listings

Function Description

The SDCS-PIN-51 provides measurement and interface circuits for ABB DC converters. It handles:

• AC input voltage measurement
• DC output voltage measurement
• Current measurement signal scaling
• Temperature measurement interface
• Hardware coding for converter voltage/current ratings

It is normally used together with the SDCS-PIN-41 / SDCS-PIN-48 pulse interface board in ABB DCS drive assemblies.

Typical Applications

Used in ABB DC drive platforms such as:

• DCS500
• DCS600
• DCS800
• High-power industrial DC motor control systems

Technical Notes

• Board type: Measurement / power interface PCB
• Weight: approximately 0.16 kg (varies by source/packaging)
• Installation: Drive cabinet internal board; requires correct hardware coding settings for the converter rating.

Replacement Considerations

When replacing an SDCS-PIN-51:

• Verify the converter frame size
• Confirm the rated voltage/current coding
• Check jumper/resistor coding configuration before installation
• Ensure compatibility with the existing SDCS-PIN interface boards
