It provides four digital PNP transistor outputs with a total output current of 4 A, making it a straightforward choice for switching small solenoid valves, indicator banks, or contactor coils on an AS-Interface network. It occupies a 22.5 mm wide footprint, matching the Slimline SC22.5 family's density for high-channel-count cabinets. Power for the output circuits must come from an external auxiliary feed (AUX POWER) of 20 to 30 V DC, compliant with PELV per IEC 60990. The module draws 45 mA from the AS-i bus at 30 V, or from an AS-i Power24V supply if available. ## AS-Interface Slave Profile and Addressing The slave profile is S-7.A.7, and the ID1 code is fixed at 7 — the setting cannot be changed via the front addressing socket. Address assignment is done through the front socket using an AS-i addressing tool; the module supports A/B slave addressing per Spec. 3.0, which allows up to 62 slaves on a single AS-i segment. Output status is indicated per channel via yellow/red LEDs on the front face. The outputs are short-circuit proof, which saves an external fuse per channel in most panel layouts. ## Wiring and Environmental Limits AWG equivalents are 20 to 16 for both solid and stranded. The IP20 rating means it's intended for a clean, dry control cabinet — no washdown or outdoor exposure. The module carries built-in induction protection on the outputs, which suppresses back-EMF from inductive loads like relays or contactors.","metaTitle":"Siemens 3RK2100-1CG00-2AA2 AS-i SC22.5 4DQ A/B I/O Module, 4","metaDescription":"Siemens 3RK2100-1CG00-2AA2 Slimline AS-i SC22.5 I/O module, 4 digital PNP outputs, 4 A total, IP20, snap-on DIN rail mounting.
