ABB DSQC-228 Discrete Input Output Module For Industrial Automation Systems

ABB DSQC-228 Safety Board (DSQC-228, YB560103-BL/2) is a discrete input/output board designed for ABB industrial automation systems. As part of ABB's DSQC family of modular I/O modules, the DSQC-228 provides digital I/O functionality that interfaces with ABB controllers and field devices within automation and robotics environments. This safety board is used to manage safety-related signals in ABB installations, such as interlocks and emergency-stop circuits, helping ensure that discrete safety logic can be monitored and actuated through ABB controllers. The designation YB560103-BL/2 appears in ABB documentation and in replacement-part catalogs and used-equipment listings, identifying the specific DSQC-228 variant. The DSQC-228 is typically deployed alongside other DSQC modules in ABB automation architectures requiring compact, card-level safety I/O to distribute safety signaling across a system. Exact channel counts, electrical interfaces, and compatible controller models can vary by installation, but the device is consistently described in listings as a DSQC-228 Safety Board used in ABB robotics and industrial automation.
