The ABB 1SAP440700R0001 DO524 is a 32-channel digital output module in the Distributed Automation I/Os family, delivering 0.5 A per channel at 24 VDC via transistor outputs. Supply voltage accepts 20.4 to 28.8 VDC, and the module carries IP20 protection for use in enclosed cabinets.
Each output sinks 0.5 A continuous; group total must respect the package limit. Panel builders should plan for the IP20 enclosure requirement — no exposure to liquids or dust.
