What sits in this slot
The ABB SM560-S (order code 1SAP280000R0001) is a safety processor module in the Distributed Automation PLC line, handling safety-related logic up to SIL 3 on the backplane rather than general-purpose control. It is a Distributed Automation PLC expansion module with 2000 kB of user-data RAM and a controller processing time of 0.00005 ms per bit operation — the figure to weigh when sizing safety task scan budget against the rest of the rack. The module exposes no on-board Industrial Ethernet and no configurable digital I/Os of its own; I/O and fieldbus are handled by adjacent TU/AI/DI/DO slices, so this card's job is the safety application itself, not signal conditioning.
The SIL figure to anchor on
The product description states the module is safety-related up to SIL 3 (SM560-S), which is the figure a safety plan gets written against when the SM560-S is dropped into a SIL 3 function. A second entry on the same listing records Safety Integrity Level (SIL) = 2, which reads as the integrated level under the configuration cited there rather than the headline module capability. When you cite this card in a safety case, anchor on the SIL 3 figure from the product description, not the lower number, and confirm the achieved level in the as-built configuration before sign-off.
Ingress and where it belongs in the panel
IP20 on the front of the module means finger-safe inside the cabinet only; it is a DIN-rail control-room device, not a field enclosure, so plan for a proper sealed cabinet when the application sits outside an MCC room. Mechanical fit follows the Distributed Automation backplane pattern — it pairs with the matching TU5xx terminal units and the PM5xx CPU in the same rack family, so existing panel cut-outs and DIN-rail layouts carry over without re-machining.
Compliance chain
RoHS statement covers EU Directive 2011/65/EU plus Amendment 2015/863 dated July 22, 2019; REACH declaration is filed with a REACH date of 20241206 and the part is flagged as containing substances above the 0.1 mass-percent threshold; SCIP reference b627bf0c-8522-41fa-9f08-dc2ad7c05d59 covers the German declaration. WEEE classification is Category 5 (small equipment, no external dimension over 50 cm) sold Business-to-Business, so end-of-life routing follows the B2B take-back path rather than consumer回收 streams.
Against the PM583 ETH sibling
The closest functional sibling in the Distributed Automation line is the PM583 ETH (order code 1SAP140300R0271): a CPU module with 2048 kB RAM, on-board LCD, one Industrial Ethernet port and serial/FBP interfaces — sized for general control rather than safety.
Sourcing reality
Production status is active, so this is a current ABB catalogue line rather than a last-time-buy; it is specified into the BOM against a quote rather than chased on the broker channel. Send the MPN and required quantity for a current lead-time and pricing posture — we quote against the official ABB channel and source to order.
