It integrates four PNP digital inputs, two PNP transistor outputs, and a built-in QuickStop function that can be wired to PIN 4 on the first two I/O sockets for emergency-stop or safety-stop logic. The module carries a watchdog timer and built-in short-circuit and induction protection, so it handles motor control and sensor feedback in one sealed unit. ## Where it goes — IP67 on the machine, not in the cabinet Rated IP67, this starter mounts directly on the machine frame or conveyor section using the K60 mounting plate (ordered separately — the module ships without one). It measures 60 mm wide by 152 mm tall by 29 mm deep, so it fits into tight machine-mount enclosures or under guarding. The 3-conductor connection scheme and PNP input circuit match standard 24 V DC sensor and actuator wiring in automated assembly and material-handling lines. ## I/O map and QuickStop wiring The four I/O sockets break out as follows: Socket 1 — PIN 4 is IN1 (D0 / QuickStop1), PIN 2 is IN2 (D1). Socket 2 — PIN 4 is IN3 (D2 / QuickStop2), PIN 2 is IN4 (D3). Sockets 3 and 4 carry the two PNP outputs on PIN 4 — OUT1 (D0) and OUT2 (D1). The sensor supply rails (L+ on PIN 1, L- on PIN 3) and a ground terminal on PIN 5 are shared across all sockets. The ID code is F; the I/O configuration is 7. Switching levels are 10 V minimum for High, 5 V maximum for Low. ## Output current and thermal limits The aggregate output current is 4 A total across both outputs. At 40 °C ambient the module supports 200 mA per output; at 55 °C that derates to 150 mA. The switching cycle limit for two 10 W DC motors at 28.8 V and 50 % duty cycle is 55 cycles per minute, with a maximum of 1500 switching operations per hour.","metaTitle":"Siemens 3RK1400-1MQ01-0AA4 Double Direct Starter, 4 Inputs 2","metaDescription":"Siemens 3RK1400-1MQ01-0AA4 double direct starter with 4 digital inputs, 2 PNP outputs, QuickStop function.
