ABB YB560103-BN DSQC 230 Robotic Computer Board

The ABB DSQC230 Robot Computer Board, part number YB560103-BN, is the DSQC-series robot CPU control board that serves as the central processing unit for ABB robot controllers. Widely listed as the DSQC 230 Robot Computer Board, and sometimes described in ABB documentation as the S3 Computer Unit, it represents the main computing module in older ABB control architectures used across various robot models. Multiple independent suppliers—Eurobots, ClassicAutomation, Radwell, BVS Electronics, and others—confirm the part as a robot computer board compatible with ABB systems, underscoring its role in handling core control tasks within the DSQC family. Professionals often source YB560103-BN when refurbishing or repairing ABB cells that rely on the DSQC 230 CPU module, making it a targeted replacement for the original main computer in legacy ABB controllers. Because it is part of ABB's older DSQC line, it is primarily encountered in maintenance catalogs and aftermarket spare-part channels, rather than current production lines.
