ABB DSQC 256A Sensor Interface PLC Card Module

ABB DSQC 256A Sensor Interface Card (model family 3HAB2211-1, with variants such as 3HAB2211-1/0 and 3HAB2211-8/1) is a DSQC 256A system board designed for ABB robotics, notably the S4C sensor-module family used with IRB robots. As a dedicated sensor interface, the module bridges external field sensors to the robot controller, enabling reliable sampling of digital and analog signals for real-time process control. Catalogued as a System Board DSQC 256A, the unit is compact and lightweight, with a typical weight around 0.3 kg. It is marketed as a sensor module board within ABB automation systems and is associated with the S4C robot range. The DSQC 256A platform supports three sensor inputs on the board, allowing multi-sensor interfacing for monitoring and control of automated processes in harsh industrial environments. Several production variants exist, including 3HAB2211-1/0 and 3HAB2211-8/1, reflecting different option sets or interface configurations used in ABB robotics installations. This module is commonly found in ABB robotics spares and automation catalogs and is used to extend sensor connectivity in complex robot cells, serving roles in data collection, status signaling, and sensor-driven control decisions.
