ABB DSQC 326 3HAB2242-1 Main Computer Board

Product Overview

The ABB DSQC 326 (3HAB2242-1) is the central computational engine designed for the S4C robot controller generation (spanning the M97 and M98 eras). As the main computer board, it acts as the "brain" of the industrial robot, responsible for executing RobotWare system instructions, managing task memory, and coordinating real-time communication between peripheral I/O and drive units.
