How to read these part numbers
Every item in this series is listed under its full Allen-Bradley part number, so the 1756-, 1756-HIST and 1756-RM 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.
