ABB DSQC254 3HAA3563-APA Backplane Circuit Board

ABB DSQC254 3HAA3563-APA Backplane Circuit Board is the DSQC 254 backplane module used in ABB robot control systems, bearing the official part number 3HAA3563-APA. It functions as the central interconnect board in DSQC 254-based controllers, providing the bus interface and mounting points for DSQC peripheral modules within ABB's modular control architecture. The 3HAA3563-APA designation is cataloged in distributor listings as a backplane suitable for a 5B Control System Backplane configuration, aligning with the standard DSQC 254 chassis layout and connector scheme used to route signals between the main controller and attached I/O boards. This backplane is part of ABB's spare-parts ecosystem for robotics and is referenced across multiple listings as the backplane for DSQC 254 assemblies. Typical applications include ABB industrial robot controllers and teach pendant backplane setups where reliable interboard connections and a compact footprint are required, and where DSQC 254-based configurations are deployed. With the 3HAA3563-APA designation, technicians sourcing a genuine ABB replacement or service part can match an exact part for maintenance or repair of DSQC 254 systems, ensuring compatibility with the DSQC 254 family and related ABB robotics hardware.
