ABB YB560103-BN Control Board DSQC230 S3 M93 Module

ABB YB560103-BN DSQC230 CPU module is the robot-control CPU board used in ABB S3/M93 controller configurations. Known as the DSQC230 Robot CPU Module, it serves as the brains of the DSQC230 computer board, coordinating the controller’s I/O, safety logic, and interconnects with the robot’s main controller. This part is identified by ABB part number YB560103-BN and is designed specifically for use with the S3/M93 family of ABB robots. In practice, the DSQC230 CPU module is paired with the DSQC230 platform to drive the run/stop sequencing, E‑stop handling, and external axis integration, enabling reliable operation in industrial automation tasks. This module is commonly referenced in vintage ABB robotics catalogs and in second-hand marketplaces as a replacement part for S3 controllers, with vendors listing it under the DSQC230/YB560103-BN designation. Typical applications include servicing or upgrading older ABB robots that rely on the DSQC230 CPU in the S3 M93 controller chain, where a compatible CPU board is required to restore control and communications between the robot controller and peripheral I/O boards. Availability is shown across multiple resellers and catalogs, including product listings for YB560103-BN DSQC230 CPU modules from ABB-compatible suppliers.
