It provides 2x2 PNP inputs and 2x2 outputs, each accessible via M12 sockets with a clear pin assignment: PIN 4 carries data input I (D0) and PIN 2 carries data input II (D1) on the first input socket, with the same pattern repeated for the second input pair and both output pairs. The module requires an external AUX POWER supply of 20 to 30 V DC for the output circuits, compliant with VDE 0106 (PELV), protection class III. The IP67 rating means the module is dust-tight and protected against temporary immersion — it can be mounted directly on a conveyor frame or machine base in a food-and-bev or automotive line without an enclosure. The 20 to 30 V DC input range covers standard 24 VDC industrial supplies with margin for brownout conditions. Built-in watchdog and short-circuit protection reduce the need for external monitoring or fusing per channel. The 6 mA minimum signal threshold and 1.5 mA maximum for signal 0 give clean discrimination on the PNP inputs, even with long cable runs to sensors. The module mounts on standard DIN rail or wall-mounts using the K60 mounting plate (delivered separately). Dimensions are 60 mm wide, 152 mm high, and 29 mm deep — compact enough for tight machine zones. Addressing is set via the front addressing socket; the ID/ID2 code is F/F. All M12 socket PIN 5 terminals are connected to the grounding wrist strap in the mounting plate via a pin, ensuring a common ground reference for the field devices. Operating temperature range is -25 to +85 °C, with storage from -40 to +85 °C, and shock resistance rated at 15g / 11 ms.","metaTitle":"Siemens 3RK1400-1DQ02-0AA3 K60 digital I/O module, 2x2 input","metaDescription":"Siemens 3RK1400-1DQ02-0AA3 K60 compact field I/O module with 2x2 PNP inputs and 2x2 outputs, IP67, 20-30 VDC, built-in watchdog and short-circuit protection.
