ABB DSQC239 Remote IO Interface Circuit Board

ABB DSQC239 Remote IO Interface Circuit Board is a dedicated Remote I/O (RIO) module that connects ABB robot controllers to field devices over the Data Highway (DH) network, enabling reliable, centralized signaling for automation cells. This board is identified by ABB part number YB560103-CH and is commonly described in catalogs and spare-parts listings as the DSQC239 Remote I/O Board, used to extend I/O reach without expanding the main controller. As a serial I/O interface (RIO) device, the DSQC239 handles the exchange of input and output data between the robot controller and remote equipment via ABB's Data Highway I/O topology. In marketplace listings and ABB spare-part references, the DSQC239 is associated with ABB robot systems such as the IRC5 family and earlier S3 configurations (including M91A and later), marking it as a recognized remote I/O option in ABB installations. Some listings reference a DSQC239 YB560103-CH/8 designation, reflecting variant labeling seen in the market. When selecting this module, verify compatibility with your ABB controller revision and the intended Data Highway I/O topology to ensure proper integration in your cell.
