The slave profile is S-7.0.F, and the module is a standard slave with a factory-set, changeable ID1 code of F. Output circuits require an auxiliary external feed (AUX POWER) of 20 to 30 V DC, compliant with IEC 60990 (PELV), protection class III. The module draws 200 mA when supplied solely via the AS-Interface bus, or 500 mA when an auxiliary supply (Uaux) is used — this matters for sizing the AS-i power supply and the AUX PELV supply. The 22.5 mm width and screw/snap-on mounting to DIN rail make it a tight fit for dense panels; depth is 120 mm, so verify clearance to the enclosure door or rear wall. Operating temperature range is -25 to +70 °C, with storage from -40 to +85 °C; shock resistance is 15g / 11 ms for the module alone, 10g / 11 ms with the device connector fitted. ## Wiring and connection notes Terminals accept 1x (0.5 to 2.5 mm²) or 2x (0.5 to 1.5 mm²) solid conductors; finely stranded with ferrules takes 1x (0.25 to 2.5 mm²) or 2x (0.25 to 1.0 mm²). AWG solid equivalents are 1x (24 to 14) or 2x (24 to 16). Stranded AWG is not permitted. Address setting is via the front addressing socket; input/output status is shown by yellow/red LEDs. The module supports 2- and 3-wire connection technology. No official successor has been announced; the 3RK1400-2CE00-2AA2 remains the active order code for this AS-i SC22.5 4DI/4DQ standard slave configuration.","metaTitle":"Siemens 3RK1400-2CE00-2AA2 AS-i SC22.5, 4DI/4DQ, Standard","metaDescription":"Siemens 3RK1400-2CE00-2AA2 Slimline Compact I/O module, 4 digital inputs, 4 digital outputs PNP, AS-Interface, IP20, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"Note":"200 mA with supply via AS interface / 500 mA with supply via Uaux","Depth":"120 mm","Solid":"1x (0.5 ... 2.5 mm²), 2x ( 0.5 ... 1.5 mm²)","Width":"22.5 mm","Height":"100 mm","ID1 code":"F; Factory setting, changeable; Factory setting, changeable","During Storage":"-40 ... +85 °C","at 30 V maximum":"270 mA","lifecycle_stage":"current","During Operation":"-25 ... +70 °C","Fastening Method":"screw and snap-on mounting","Product Function":"Built-in induction protection","Shock Resistance":"15g / 11 ms (modules) or 10g / 11 ms (modules with device connector)","for AS-Interface":"2 A","Other Information":"An auxiliary external feed (AUX POWER) of between 20 and 30 V DC is necessary for supplying the output circuits.
