It is designed as a standard slave (ID/ID2 code 0/F) and communicates exclusively over the AS-Interface protocol. The module draws its power and sensor supply from the AS-i bus, accepting an input voltage of 26.5 to 31.6 V DC. The four inputs are PNP type, with a switching voltage range of 20 to 30 V DC. Total current available for all inputs and outputs is 200 mA, with a maximum AS-i bus draw of 270 mA. The sensor supply is short-circuit and overload resistant. ## Where it fits — integration context This module is an open-board design rated IP00, meaning it has no enclosure and is intended for integration inside a larger assembly or panel where the environment is clean and dry. It mounts via a card-edge board-to-board connector, not a DIN rail. The dimensions are compact: 75 mm wide, 54 mm deep, and only 9 mm high. The 30-pole male connector socket handles all field wiring for the four inputs. The LED status display shows AS-i communication health (green), faults (red), and input status (yellow), with specific blink patterns for zero address, no data traffic, and sensor overload.","metaTitle":"Siemens 3RK1200-0CD00-0AA2 AS-i PCB Module, 4 DI, IP00","metaDescription":"Siemens 3RK1200-0CD00-0AA2 AS-Interface PCB module with 4 digital inputs for 3-wire sensors.
