ABB YB560103-CB Printed Circuit Board Assembly

ABB YB560103-CB Printed Circuit Board Assembly is a nine‑circuit drive board in the ABB DSQC 236B family, used within ABB control systems to manage multiple feedback and control channels on a single PCB. The part originated with ASEA BROWN BOVERI and is cataloged by ABB as YB560103-CB, with the 9‑circuit variant commonly listed as YB560103-CB/9. Retail listings identify this item as discontinued by the manufacturer, which explains its typical availability as surplus or used stock. As a DSQC 236B drive board, it functions as a multi‑channel interface within ABB drive modules, coordinating several control signals across the DSQC 236B architecture. Related listings also reference similar SKUs (such as YB560103-CB/11) that pertain to the same core component, indicating variant documentation across different catalogs. When replacing this board, verify exact connector types, pinouts, and signal level expectations against the specific ABB drive or robot controller model to ensure compatibility. This PCB is commonly encountered in industrial automation applications that rely on ABB servo drive systems and robotics controllers, where a nine‑circuit board serves as a compact, integrated interface for parallel control tasks.
