What the S200-RPA actually is
The ABB S200-RPA is a repeater adapter module within ABB's PLC expansion line, identified on the row as a PLC Expansion Module under the PLCs and Accessories family.
Reading the spec sheet for what matters
The only quantitative figure the listing carries for this order code is a mass of 0.18 kg. That figure matters to the panel builder for DIN-rail handling and to the MRO planner for spare-kit weight, not as a functional rating — the electrical envelope of a repeater adapter is governed by bus protocol, segment current draw and isolation class, none of which are quoted on this row and so none of which can be asserted here. A buyer treating this module like a contactor or a drive will over-weight the wrong number; the figure to weigh against a panel layout is the 0.18 kg mass and nothing more from this row.
Where this class sits on a panel
In the broader PLCs and Accessories family, a repeater adapter is the piece you reach for when the S200 backplane needs to bridge to a remote drop or to extend the I/O segment past the head's native limits. From an integration standpoint it occupies a single DIN slot and draws its operating power from the bus segment it sits on, so the real engineering questions are segment loading and cable-length budget rather than the module's own electrical ratings — those concerns are answered by the bus topology rather than by the S200-RPA row itself. Where the panel layout already specifies a repeater adapter slot, the S200-RPA is the ABB-branded fill for that slot.
