It connects via M12 screw-type terminals and uses the AS-Interface bus for both power and communication, drawing up to 290 mA total from the AS-Interface line. The module is a standard slave (ID code 1) and accepts input voltages from 20 to 27 V DC, with a switching threshold of 10 V minimum for a High signal. IP67 means the module is sealed against dust and temporary immersion — suitable for washdown zones in food, beverage, or packaging lines where sensors and actuators are mounted directly on the machine frame rather than in a central cabinet. The housing is 80 mm tall, 45 mm wide, and 27 mm deep, and mounts on standard DIN rail or to a wall via the coupling module. ## Integration notes The module has 4 I/O sockets (user modules) and uses 2- and 3-wire technology for the inputs. Pin assignment: PIN4 = IN1 (D0), PIN2 = IN2 (D1) on socket 1; socket 2 repeats PIN4 = IN2 (D1); socket 3 has PIN4 = IN3 (D2), PIN2 = IN4 (D3); socket 4 has PIN4 = IN4 (D3). The sensor supply from the AS-Interface bus is short-circuit and overload resistant. Inputs are NPN, so the load connects between the positive supply and the input — verify polarity before wiring.","metaTitle":"Siemens 3RK1200-0CQ01-0AA3 AS-Interface Module, 4 Inputs NPN","metaDescription":"Siemens 3RK1200-0CQ01-0AA3 AS-Interface digital I/O module, 4 NPN inputs, IP67, 20-27V DC, current production.
