What the module carries
The ABB 1SAP260300R0001 is a CD522 function module from the Distributed Automation I/Os family — a slice that handles 2 encoder inputs, 2 PWM outputs, 2 DI 24VDC, and 8 configurable DI/DO 24VDC on a single block. The encoder inputs are what separates this module from a plain digital slice — they are the path for shaft feedback into a positioning or speed loop, while the PWM outputs pair with them to drive proportional valves, proportional solenoids, or small DC actuators that need a duty-cycle signal rather than a binary command. The 8 configurable DI/DO channels are software-selectable per channel between input and output, which is useful on a machine where the final tally of sensors versus actuators is still being settled at commissioning time — a few extra points can be flipped without pulling a different module.
Enclosure and ambient envelope
The housing is rated IP20, so the module is designed to live inside an enclosed cabinet away from operator reach — it is not a panel-face device and must not be specified for field mounting without additional protection. Operation is rated for ambient air temperature 0... +60 °C, which is the standard envelope for a control-cabinet-mounted slice but worth noting when the cabinet sits next to a VFD or a soft-starter that pushes internal temperature up — the 60 °C ceiling is the wall, not a suggestion. Like the rest of the ABB Distributed Automation I/Os family, the module carries the EU customs code 85389091 and falls under WEEE Category 5 (small equipment, no external dimension more than 50 cm) on a business-to-business take-back scheme, which matters for end-of-life paperwork in EU installations.
Compliance paperwork reviewers will ask for
ABB declares the module compliant with EU Directive 2011/65/EU and Amendment 2015/863 of 22 July 2019 on RoHS, and the SCIP dossier for the part is registered as 2084bd69-e6ed-40c9-ac25-8cac44e581ca in Germany. REACH disclosure is on file with a reference date of 20241206, and the part contains substances above 0.1 mass percent — flagged as 'True' in the declaration, so the SVHC >0.1% line on the decl pack must be completed rather than left as 'no substances above threshold'.
