The module draws its sensor supply from L+ (PIN 1) and L- (PIN 3), with the output on PIN 2 and data input on PIN 4 — PIN 5 serves as a common ground terminal, daisy-chained via a flat tab sleeve. Total current across all inputs and outputs is capped at 200 mA per module, so plan your sensor and actuator loads accordingly. Rated IP67, the module handles washdown environments — common on conveyor and packaging lines where dust and hose-down are routine. Mounts on standard DIN rail or to a wall using the optional K45 mounting plate (the module ships without one). The front addressing socket and built-in watchdog simplify commissioning on an AS-Interface network (A/B slave, Spec. 3.0).","metaTitle":"Siemens 3RK2400-0GQ20-0AA3 K45 Digital I/O Module, 4 x (1 IN","metaDescription":"Siemens 3RK2400-0GQ20-0AA3 K45 field I/O module, 4 x (1 input / 1 output) PNP, IP67, 20-30 VDC, 0.2 A max per module.
