The 1SAP224200R0001 is an ABB CI542 PROFIBUS slave module that gives a system 8 digital inputs at 24 VDC, 8 transistor outputs rated 0.5 A, and 8 channels that can be software-configured as either input or output at the same voltage and current. The supply rail runs between 20.4 and 28.8 V DC, which matches standard 24 V control panels without a separate power bus. Because the configurable bank is in the same package, one spare part covers mixed I/O needs on the same node.
The transistor output stage (0.5 A per channel) handles solenoid valves, indicator lights, and small contactor coils directly – no external relay needed as long as the inrush stays within the DC limit. The configurable channels offer a 5 mA input current (the Input Current spec), which is standard for 24 V PLC inputs, so legacy field wiring from an older PROFIBUS node can move to this module without signal conditioning. No analog I/O on this board – it is strictly digital; if the BOM needs analog, this is not the slot.
The product lifecycle is marked as current, and the ABB production status is Active. That means it is still being manufactured, stocked through distribution, and supported with documentation. No end-of-life notice or last-time-buy horizon is on the table. For a BOM that needs a PROFIBUS remote I/O module, this is a standard catalogue item – order against RFQ and expect normal lead times through the distribution channel.
IP20 enclosure fits inside a control cabinet; no glands required. The module communicates via PROFIBUS DP – no Ethernet interface on board, so it is a pure PROFIBUS slave. The delay time can be set from 0.1 to 32 ms, which gives enough filter flexibility for noisy environments or fast proximity sensors. WEEE classification is Business To Business (B2B), so end-of-life disposal follows the company's electrical waste protocol.
