ABB 3HAA3573-ADA Robot Controller

ABB 3HAA3573-ADA is a 6 MB memory expansion card for ABB S4 robot controllers, designed to add RAM for RAPID programs and data to support larger, more complex automation tasks. This memory module corresponds to the 3HAB2220-1 backplane card and is commonly documented as the DSQC317 extended memory board, rated for installation in ABB S4 systems with a 25 MHz clock reference. Compatible with ABB IRB robots and older S4 platforms—including M94 and M94A configurations—the 6 MB card enables expanded program storage and data tables without replacing the main controller. Cataloged as DSQC317/M.exp 6Mb, it is a standard option in ABB robot systems where memory expansion is required to handle bigger control programs and datasets.
