ABB DSQC327A Combination Digital Input Module

ABB DSQC327A Combination Digital Input Module (order code 3HAC17971-1/05) is a combi I/O board that adds digital input and digital output capability to ABB automation systems and robot controllers. The module is designed for central or decentralized I/O expansion and is typically mounted inside the ABB control module or connected to a non-ABB external I/O unit, with a separate 24 VDC power supply provided by the user. It interfaces with standard 24 VDC logic signaling and consolidates I/O channels into a single plug‑in module to streamline wiring and improve real-time responsiveness for sensing and actuation tasks in manufacturing environments. This DSQC327A supports ABB’s automation ecosystems, including integration with Robot Controllers and System 800xA environments, making it a compact, scalable solution for expanding digital I/O in industrial automation setups.
