Features:
- AC and DC voltage scaling and is verified against the exact ABB hardware marking and installed configuration before replacement.
- Armature-current measurement and is verified against the exact ABB hardware marking and installed configuration before replacement.
- Heat-sink PTC interface and is verified against the exact ABB hardware marking and installed configuration before replacement.
ABB identifies SDCS-PIN-H51 3ADT320700R1501 as sdcs-pin-h51 power-stage measurement board for ABB DCS880 rebuild and DC-drive power-stage systems. ABB states that one SDCS-PIN-H51 is required per applicable rebuild kit. The board interfaces a heat-sink PTC sensor, measures and scales AC/DC voltage through high-ohmic resistors, and scales armature current through burden resistors to 1.5 V at rated power-stage current. Selection must be based on the complete ordering identity and installed hardware context because related models can differ in mechanical arrangement, interfaces, cable configuration, approvals or supported system generation.
Before replacing SDCS-PIN-H51 3ADT320700R1501, record the installed position, hardware revision, mounting or connector arrangement, paired assemblies and every applicable ABB service record. Compare the supplied unit with the original item and approved configuration, isolate all relevant energy sources, and follow the documented installation procedure. After installation, inspect every affected mechanical, electrical and communication interface and complete controlled functional checks before returning the equipment to service.
The SDCS-PIN-H51 3ADT320700R1501 ABB Measurement board is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.

Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
Measurement Functions
The board provides PTC temperature input, AC/DC voltage scaling and armature-current measurement for the power stage.
Coding Dependencies
Line voltage, power-stack current, CT ratio, burden resistors and controller scaling parameters must be established for the actual application.
Installation Grounding
Use the supplied card holder, preserve conductive grounding points and insulated supports, and verify terminal clearances before energization.
