The ABB 1SAP140300R0271 is the PM583-ETH processor module, listed under the Distributed Automation PLCs product main type PM583 — a CPU unit, not an I/O slice. On the front: one industrial Ethernet port, two serial ports covering RS232 and RS485, an FBP (fieldbus plug) interface and an on-board LCD for diagnostics and address handling.
Memory and cycle
Total memory is 2048 kB, split 1024 kB of user program and 1024 kB of user data in RAM — the split matters for sizing structured-text and recipe blocks: program goes one way, tag/recipe storage the other, and they cannot borrow from each other once full. Controller processing time is 0.00005 ms per bit operation, which is the cycle-budget figure to read when matching scan time to fast-loop I/O — the headline 2048 kB capacity does not on its own tell you whether a 1 ms loop closes.
Supply and ambient envelope
Supply voltage is 24 V DC rated, accepted over a 20.4 to 28.8 V DC window — a common 24 V DC rail feeds the CPU without a separate converter. Ambient operating temperature is 0 to +60 °C, so the module lives inside a closed cabinet with whatever panel cooling the rest of the system already specifies; nothing on the rating pushes it to the cold or outdoor side of the envelope. Degree of protection is IP20, which is the standard enclosed-cabinet figure for DIN-rail-mounted PLC sub-assemblies — it is not a wet-well or hose-down rating.
Compliance pack on file
RoHS conformity follows EU Directive 2011/65/EU with Amendment 2015/863 dated 22 July 2019, REACH declaration is true (contains substances above 0.1 mass percent), and the SCIP database identifier is filed for traceability into EU substance-of-concern filings. WEEE classification is category 5 small equipment under B2B channels only — relevant for end-of-life routing, not for cabinet specification.
Sourcing posture
Lifecycle status is active, so the line is quoted to order against the BOM rather than chased on the broker channel — when the order code hits the BOM, an RFQ against this code is the right move.
