How to read these part numbers
Every item in this series is listed under its full Siemens part number, so the 6ES73 reference on the nameplate is the reference to search. Where a part number exists in more than one hardware or firmware revision, the revision recorded for the item appears on its product page. Specifications not recorded in our catalogue for a given part number are confirmed with the sourcing team before quoting.
