ABB SDCS-PIN-H51 is the measuring board used in DCS880 converter frame sizes H6 through H8. It acquires armature-current and AC/DC-voltage measurement signals for the converter control system.
- Routes isolated power-stage measurements toward the control electronics
- Interfaces with the H6-H8 converter power circuit
- Supports current feedback used by the regulated armature loop
- Provides voltage-measurement paths used by converter monitoring
SDCS-PIN-H51 operates with SDCS-CON-H01 control board, H6-H8 power module, firing pulse transformer boards, converter measurement wiring.
Typical engineered duties include DCS880 H6-H8 converter service, DCT880 power-controller maintenance, Armature feedback troubleshooting, Power-stage board replacement.
Important Notice: Match SDCS-PIN-H51 and spare part 3ADT320700R1501 to the converter frame, board revision, connector layout and service documentation before installation.

Read the applicable ABB installation instructions before work. Verify SDCS-PIN-H51 and the installed-system configuration.
1Discharge the DC circuit and prove isolation before opening the converter.
2Record every connector designation before removing the board.
3Use ESD controls and protect measurement connectors from contamination.
4After replacement, verify current and voltage feedback before enabling the power stage.
5Commission SDCS-PIN-H51 under controlled conditions and retain the completed functional-test record before release.
