An internet search using AI gave me the following results:
The DSQC639 was available from ABB in several versions with corresponding part numbers: 3HAC025527-004 is the original or older part number for this computer unit. 3HAC041443-003 is the current or replacement part number used by ABB/replacement parts suppliers today—both numbers refer to the same part.
Both versions are compatible/identical!
Is this correct? Can anyone confirm this?
Because the number doesn’t tell anything about the installed motherboard, does it?
3HAC025097-001 - This is the mainboard bare, without a complete metal case, but with various hardware versions:
• 3HAC025097-001/08
• 3HAC025097-001/11
• 3HAC025097-001/13
• 3HAC025097-001/1
Is there an overview of the mainboard versions? What are the performance differences? What about compatibility? Can you see in the backup which mainboard/computer is installed?
Thank You
Daniel
