What lands in the panel
The ABB 1SAP245200R0001 is the DX522 digital input/output module — 8 digital inputs at 24 VDC with 8 relay outputs in a single module, so signal and load wiring land on one terminal row.
Read the relay rating, not the headline count
Each of the 8 outputs is a relay contact rated 3 A into an AC load, with the allowable output voltage window running 195.5 to 276 V — that is the spec that decides what the contacts actually switch, and it sets the ceiling for any solenoid, contactor coil, or indicator lamp the DO is asked to drive on the AC side. Supply input runs 20.4 to 28.8 V DC; digital inputs accept 0 to 30 V DC at 5 mA per point, and the input filter is configurable from 0.1 to 32 ms to debounce mechanical switches.
Where it sits and where it does not
IP20 marks this as a panel-internal device — the DX522 belongs inside an enclosure, not out at the field device, so cable runs from the sensors and the switched AC loads land back at the cabinet on terminal blocks.
Production status and the doc pack
Compliance paperwork on file covers EU Directive 2011/65/EU with the 2015/863 amendment for RoHS, a REACH declaration dated 2024-12-06 noting substances present above the 0.1 mass-percent threshold, and a SCIP reference for the German market — the documentation a purchasing file needs when the BOM line is opened or audited.
