Data Sheet: ABB DSQC256A 3HAB2211-1 Axis & I/O Control Module
Purpose & Position
DSQC256A (part no. 3HAB2211-1) is a multi-function control card used inside ABB S3 / S4 robot controllers. It hosts motion algorithms, servo-loop closure, and mixed I/O interfacing for up to 6 axes and 16 digital channels, all on a single 3U Eurocard.
Distinctive Features
• One-card motion + I/O – reduces rack slots by 30 % compared to separate axis and I/O cards.
• Absolute encoder battery backup – retains robot position for > 48 h after power loss.
• Hot firmware reload – firmware update via serial port without removing the card.
• Spring-cage terminals – accept 0.2–2.5 mm² wire, no ferrules needed.
Typical Applications
• IRB 140 / IRB 2400 welding cells
• IRB 4400 palletizing lines
• IRB 6400 press-tending systems
• Retrofit of legacy S3/S4 controllers to extend service life
