DSQC104 | ABB Robot Motion Feedback | 16-Bit Resolution

Product Description

Precision Motion Feedback and Signal Conversion

The DSQC104 (Model: DSQC104) is a high-precision resolver interface board engineered for ABB industrial robot controllers, spanning legacy S3 and S4 systems to modern IRC5 architectures. As a fundamental component of the motion control loop, the DSQC104 (Part Number: DSQC104) processes raw analog signals from motor-mounted resolvers (rotary transformers). It converts sine/cosine wave inputs into high-resolution digital position and velocity data, enabling the robot's main computer to execute complex path planning with sub-millimeter accuracy.
