It packs four digital inputs (PNP) and one PNP transistor output, plus a built-in QuickStop function that can be wired to either of the two AS-Interface sockets for an emergency stop or safe-off signal. IP67 means the housing is dust-tight and protected against temporary immersion — suitable for washdown zones on packaging or food-and-beverage lines where a standard panel-mount starter would need an extra enclosure. The 20 to 30 V DC supply range covers nominal 24 V systems with headroom for brownout conditions. The PNP input circuit is standard for most PLC and sensor families; the switching threshold is High ≥ 10 V, Low ≤ 5 V, so it works with 24 V logic without level shifting. The sensor supply on PIN 1 (L+) is short-circuit and overload protected, rated 200 mA at 40 °C and 150 mA at 55 °C — enough for a handful of proximity sensors or a small photoelectric eye, but not for a bank of valve solenoids. This is a wall-mount module using the K60 mounting plate (sold separately — the module ships without it). The footprint is 60 mm wide × 152 mm high × 29 mm deep, so it fits in a small junction box or on a machine frame. Three AS-Interface sockets handle the I/O: socket 1 carries IN1 (D0/QuickStop1) and IN2 (D1); socket 2 carries IN3 (D2/QuickStop2) and IN4 (D3); socket 3 is the single PNP output (OUT1 on D0, D1).","metaTitle":"Siemens 3RK1400-1MQ03-0AA4 motor starter IP67, 4 inputs, 1 o","metaDescription":"Siemens 3RK1400-1MQ03-0AA4 single reversing starter, 4 digital inputs, 1 PNP output, QuickStop function, IP67, 24 V DC, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"Type":"single reversing starter, 4 inputs, 1 output, QuickStop function","Depth":"29mm","PIN 1":"sensor supply L+","PIN 2":"data input","PIN 3":"sensor supply L-","PIN 4":"data input/QuickStop","PIN 5":"ground terminal","Width":"60mm","Height":"152mm","Note 1":"max. number of switching operations when controlling a 10 W DC motor for example (Uaux = 28.8 V/duty cycle = 50 %): Tumax/C: 55, max. number of switching operations/h: 1000","Socket":"PIN4 = IN1 (D0 / QuickStop1), PIN2 = IN2 (D1)","ID code":"F","Socket 2":"PIN4 = IN3 (D2 / QuickStop2), PIN2 = IN4 (D3)","Socket 3":"PIN2,4 = OUT1 (D0, D1)","Watchdog":"built-in","Delivery note":"the modules are delivered without mounting plate","Input Voltage":"20 ... 30V","Input circuit":"PNP","During Storage":"-40 ... +85°C","Ground terminal":"yes","lifecycle_stage":"current","During Operation":"-25 ... +55°C","Fastening Method":"wall mounting using K60 mounting plate","I/O configuration":"7","Number I/O sockets":"3","protection class IP":"IP67","Induction Protection":"built-in","Design Of The Product":"motor starter IP67 (24 V DC)","Short-Ciruit Protection":"built-in","switching level Low max":"5V","Design Of The Slave Type":"standard slave","Number Of Digital Inputs":"4","Type Of Switching Output":"PNP transistor","switching level High min":"10V","Number Of Digital Outputs":"1","Type Of Connection Technology":"3-conductor","at ambient temperature 40 °C":"200mA","at ambient temperature 55 °C":"150mA","Voltage Drop Without Supply Line":"1.2V","sensor supply using AS-Interface":"short-circuit and overload resistant","Type Of Voltage Of Output Voltages":"DC","AS interface total current input max":"270mA","Inputs external power supply 24 V DC":"using black AS-Interface cable","Type Of Voltage Of The Input Voltages":"DC","Inputs start-up ramp time DC motor max":"801/s","Property Of The Output Short-Circuit Proof":"Yes","Input Current At Digital Input For Signal <1> Minimum":"6mA","Type Of Electrical Connection Of The Inputs And Outputs":"M12 screw-type terminals","operating voltage according to AS-Interface spezification":"26.5 ... 31.6V","rated current carrying capacity per output Tu: max 55 Cel":"2.5A","Output Current At Digital Output For Signal <1> Rated Value":"2.5A","Inputs Start-up current Motor (limited by internal module design)":"4.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$392.43","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=282621&mlfb=3RK1400-1MQ03-0AA4","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RK1400-1MQ03-0AA4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source — 3RT1036-1AB00?","answer":"The 3RT1036-1AB00 is a conventional contactor, not an IP67 motor starter with integrated AS-Interface I/O and QuickStop.
