What it does on the panel
The ABB 1SAP220700R0001 is a CI502-PNIO distributed-automation interface module that sits on a PROFINET IO RT network and exposes 8 digital inputs, 8 digital outputs, and 8 channels that can be configured as either DI or DO to the controller, all on 24 VDC. Each digital input is specified for 24 VDC at 5 mA, so the 24 V rail sizing exercise is per-channel count multiplied by that 5 mA figure rather than a separate surge envelope. The transistor outputs are rated 0.5 A at 20.4... 28.8 VDC, which is the working envelope you wire against for indicator lamps, relay coils, and small solenoid valves — not for direct motor switching. Two Industrial Ethernet ports are provided, which is enough to daisy-chain adjacent PROFINET devices in line topology without dropping an external managed switch into that segment. Signal-exchange delay sits in the 0.1... 32 ms window, so the module is well-behaved on standard discrete I/O but you do not size it as a high-speed counter front-end.
Sourcing posture
Production status is active, so the order code is still being built and a fresh BOM line is supported without last-time-buy negotiation. The compliance pack carried with the part includes RoHS to EU Directive 2011/65/EU with Amendment 2015/863 dated July 22, 2019, REACH substance declaration dated 20241206, and a SCIP entry 2052f720-cc65-48e9-8837-6572a99672cf filed for Germany. For a procurement line that needs RoHS and REACH traceability on the shipping packet, the documentation is there — nameplate versus PO cross-check is the normal QA step.
Where the relay-output sibling differs
Where the panel calls for switching 230 VAC loads directly — a heater interlock or a small contactor coil — the same-class ABB 1SAP245200R0001 (DX522) keeps the 8 DI at 24 VDC but substitutes 8 relay outputs rated 3 A at 195.5... 276 V, which is the part-class decision that actually changes the BOM rather than the channel count.
