What the part is
The ABB 1SAP170700R0001 sits in the PLCs and Accessories line as a PLC expansion module — the ASEA BROWN BOVERI order code under the ABB brand, intended to plug into an ABB PLC rack alongside other PLC expansion modules on the backplane. At 0.05 kgs the module is light enough that one person handles it without lifting aids, which matters when a panel builder is populating a dense DIN segment with several expansion modules in series and counting slot mass against the rack's mechanical budget.
Fit and panel-side considerations
Because the part is catalogued under PLC Expansion Modules rather than a controller or HMI, it is expected to share form factor with the rest of that family — same DIN-rail footprint, same backplane connector keying, same terminal layout family as other entries in the PLCs and Accessories line. For an integrator, the practical consequence is straightforward: when a panel was laid out around an ABB expansion slot pattern, the 1SAP170700R0001 should land in the next free slot without re-drilling the gland plate or rewiring the backplane, provided the original spec called for this module family in that position.
