The ABB 3AXD50000033791 is the RIIO-01 I/O module with Modbus RTU — an I/O slice on the PLC expansion side of the rack, not a CPU and not a power supply, carrying its fieldbus on the RTU link as printed in the title block. Lifecycle on this order code reads active, so a BOM line that names 3AXD50000033791 stays specified without a last-time-buy clock on it. The RoHS declaration on file is dated 20230315 against EU Directive 2011/65/EU and the 2015/863 amendment of July 22, 2019, which closes the materials-compliance leg of the decl pack. REACH is filed negative: the product is stated not to contain substances above the 0.1 mass percentage threshold, which is what an inspector scanning the decl pack is reading for.
Compliance posture, plain text
WEEE classification on the listing is Product Not in WEEE Scope, so the part sits outside the standard Small/Large Equipment bins a site team is used to routing through; track it through whatever scrap line your EHS procedure uses for non-scope electronics. The decl pack on file is the RoHS/REACH record above; no UL, IEC, or ATEX strings appear on this listing for 3AXD50000033791.
