What the S200-ANN is
The ABB S200-ANN is a PLC expansion adapter in the PLC Expansion Modules line, carrying a listed mass of 0.18 kg and shipped as the ASEA BROWN BOVERI part number S200-ANN. It sits one rung below the controller in the rack: the kind of card you snap into a free expansion slot to bridge an ABB PLC base to a downstream I/O island or communication slice, not a standalone controller in its own right.
What the listed ratings actually tell you
The only quantified figure the listing carries is 0.18 kg of mass, which means a single-handed module at panel-build — no lift plan, no two-person swap, and no cabinet-reinforcement math when you add it to a populated DIN sub-panel.
Where the S200-ANN class fits in a panel
PLC expansion adapters of this kind are used to add a slice of I/O or a fieldbus gateway onto an existing ABB controller backplane when the base unit has run out of local slots but the cabinet still has DIN rail and gland-plate real estate, so the S200-ANN is the kind of part a controls integrator reaches for during a late-stage BOM freeze rather than a green-field spec.
Cross-reference posture
The nearest same-class peer on file, 3BSE013237R1, is listed at 0.17 kg versus 0.18 kg for the S200-ANN. The swap question is mechanical and electrical fit, not weight. Treat any move to 3BSE013237R1, 1SVR040013R2701, or 07 EB 61 R1 as a quoted-to-order cross-reference conversation, not a guaranteed drop-in: the listing confirms they share the expansion-module class, not pin-for-pin compatibility.
Sourcing posture and buyer close
ABB is the listed brand on the S200-ANN, and the part is specified into the BOM against an RFQ rather than pulled from a generic catalog line — quote it against the order code and the listed 0.18 kg figure is what your receiving inspection weighs against, nothing more.
