What lands on the bench
The ABB S200-OB16P sits in the PLCs & HMIs line as a PLC expansion module, catalogued under PLCs and Accessories / PLC Expansion Modules, with the part number S200-OB16P carried verbatim on the nameplate line. At 0.17 kgs the module is a one-handed DIN-row swap. Pull it from stores, slot it into the carrier, restore the I/O. Beyond the part number, the mass, and the category trail, no further functional ratings (channel count, voltage class, fieldbus slice, isolation) are carried on the spec sheet that reached this listing, so anything beyond that envelope — wiring diagram, terminal map, firmware slot — has to come from the manufacturer's documentation rather than from this page.
Where the S200 prefix sits against modern ABB article numbers
The ABB 3BSE013237R1 and 1SVR040013R2701 share the same category trail and the same 0.17 kgs mass as S200-OB16P, so a panel specified around 3BSE013237R1 is the natural place to verify whether S200-OB16P is the same card under a different order code. A 0.17 kg vs 0.64 kg gap against 129A542G01 means that peer is a different physical module rather than a like-for-like alternative, and the correct response is not to call it a substitute.
Commissioning checklist cadence
Before energising, confirm the slot address and carrier position against the controller's I/O map and firmware slot — the spec sheet carried here does not list those, so they belong on the SAT sheet rather than on the RFQ. Record the part number as it appears on the nameplate (S200-OB16P) and the declared mass (0.17 kgs) on the decl pack so the PO line, the FAT sheet, and the installed-as tag all trace back to the same identity.
