        • PRODUCT OVERVIEW

          What is this product?

          ABB 3HAC031977-001, described as a dsqc 633 serial measurement unit, combines a DSQC 633 serial-measurement board with the assembly used for robot axis-position feedback. Selection must match the complete assembly number, robot parts list, base compartment, battery contact and connector layout. During service, protect the electronics from ESD, retain cable identification and update revolution counters when ABB procedures require it.

          Selection boundary

          Use the complete ABB article number, installed configuration and applicable official ABB documentation; visual similarity does not establish interchangeability.
        • APPLICATIONS

          Robot-base feedback renewal

          Used where the installed robot base and parts list call for the same complete measurement assembly.

          Position feedback service

          Restores the documented serial-measurement path after an assembly fault.

          Base compartment repair

          Fits maintenance work performed inside the robot's designated electronics space.

          Battery contact matching

          Preserves the specified battery connection used by the feedback assembly.

          Counter recommissioning

          Supports the required axis-reference checks before returning the robot to motion.
