What lands in the panel
The ABB 1SAP240100R0001 is the DC532 in the Distributed Automation I/O line — a digital input/output module that drops into the ABB PLC I/O rack to add 16 dedicated 24 VDC digital inputs and another 16 channels that can be set per channel as either a digital input or a 24 VDC 0.5 A transistor output. That mixed fixed-plus-configurable layout is the reason it is on a BOM instead of a plain DI slice: the configurables let the integrator absorb both a handful of leftover discretes and the small solenoid/relay coils that would otherwise force a second output module onto the bill of materials. Signal-exchange delay is 0.1 to 32 ms across the configurable channels — fast enough for general discretes and most pushbutton/status work, but the integrator thinking about high-speed counting or pulse measurement should not assume this slice covers it; that duty belongs on a counter/fast-I/O module. Maximum input voltage is 0 to 30 V, and supply voltage is 20.4 to 28.8 V DC — a normal plant-rail transient stays inside the input rating.
Cabinet-resident, not field-resident
Degree of protection is IP20, which means the module is built to live on a DIN-rail backplane inside a sealed enclosure — not on a wet-well wall, not on an unistrut next to a digester. For any application where the cabinet itself floods or where condensation runs down the DIN rail, the enclosure has to carry the ingress rating, not the module. WEEE Category 5 (small equipment, no external dimension over 50 cm) and B2B classification confirm the unit is intended for professional integration into a machine or panel, not a consumer end-product — the scrap/recovery path goes through the panel builder's compliance flow, not a retail take-back.
Lifecycle and compliance pack
Product status is active, so the module is specified into the BOM as a current-production ABB Distributed Automation I/O part — quoting is handled against the order code via RFQ rather than a last-time-buy window. Compliance documentation on file: RoHS conformance to EU Directive 2011/65/EU and Amendment 2015/863 dated 22 July 2019; REACH disclosure on file as true (contains substances above the 0.1 mass percentage threshold), with a REACH declaration date of 2024-12-06 and a SCIP identifier of 37dc1f5d-8a13-4e11-9ee5-efcbc63dab42 filed for the Germany market — the doc-control buyer can attach those IDs to the declaration pack without a further request. Customs classification under CN8 is 85389091, which is the code that flows onto the import declaration for this part — match it against the PO line before shipping so the customs broker does not have to amend the entry after the fact.
Closest functional sibling — what is and isn't a drop-in
Outside that one direct comparison, the 1SAP212000R0001 (TU516) is a terminal unit for analog and 24 VDC digital modules, and the 1SAP250300R0001 (AI523) is a 16-channel analog input slice for U/I/RTD/DI at 13-bit resolution — both belong to the same Distributed Automation I/O family but neither is a functional alternative to the DC532.
