It accepts 2/3/4-conductor sensors and is configurable for 1... 5 V or ±10 V ranges with 14-bit A/D resolution. Rated IP67, it is built for field mounting — washdown zones, wet environments, or anywhere you need to digitize a voltage signal (pressure transmitter, level sensor, potentiometer feedback) right at the machine without a separate enclosure. The module draws its operating power from the AS-Interface cable (26.5... 31.6 V) and provides a separate auxiliary sensor supply (Uaux) at 24... 30 V, capable of sourcing up to 500 mA for external sensors. Without the aux supply, the module itself consumes 46 mA max from the AS-i bus. Mounts via standard rail or wall mounting using the K60 compact module mounting plate (3RK1901-0CA00, ordered separately). The 60 mm width, 152 mm height, and 29 mm depth fit a standard DIN-rail footprint — plan for the mounting plate in your BOM. Sensor connections are via two M12 screw-type sockets (4-conductor), one per analog input channel. The AS-Interface bus and auxiliary power connect through the module's integrated profile conductors — no separate power wiring needed for the bus side. Two analog inputs, zero analog outputs — this is a pure measurement module, not a control output device. If your application needs analog output (e.g. driving a proportional valve), you need a different K60 variant. The configurable smoothing function lets you dampen noisy signals at the module level, saving a filter block in the PLC. The ID code 'A' and I/O configuration '7' are fixed for this slave type — the AS-i master recognizes it automatically. Operating temperature range -20... +60 °C, storage down to -40... +85 °C — suitable for unheated plant floors and seasonal storage. The red FAULT LED and green AS-Interface / AUX PWR LEDs give quick visual status without a handheld tool.","metaTitle":"Siemens 3RK2207-2BQ50-0AA3 AS-i K60 Analog Module, 2 AI, IP6","metaDescription":"Siemens 3RK2207-2BQ50-0AA3 AS-Interface compact module K60, 2 analog inputs for voltage (1-5 V / ±10 V), 14-bit A/D, IP67, M12 connections, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Remote I/O & Fieldbus Modules"],"specifications":{"Type":"2 inputs","Depth":"29mm","FAULT":"red LED","Width":"60mm","Height":"152mm","ID code":"A","Profile":"7.A.9","Voltage":"Yes","AS-Interface":"green LED","AUX PWR (Uaux)":"green LED","During Storage":"-40 ... +85°C","Input Variable":"V","Inputs sensors":"2/3/4-conductor sensors","Type of device":"analog input modules for voltage measurement","Channels active":"1 and 2","lifecycle_stage":"current","During Operation":"-20 ... +60°C","Fastening Method":"standard rail mounting/wall mounting using mounting plate for K60 compact module","I/O configuration":"7","Smoothing function":"configurable","protection class IP":"IP67","Design Of The Product":"analog I/O modules for operation in the field, IP67 - K60","from Uaux infeed max.":"500mA","Measuring/output range":"adjustable: 1 ... 5 V / +-10 V","Measuring/output value":"voltage","Number Of Analog Inputs":"2","without Uaux infeed max":"46mA","Design Of The Slave Type":"A/B analog slave (Spec. 3.0)","Number Of Analog Outputs":"0","Type Of Connection Technology":"4-conductor","A/D resolution for analog inputs/outputs":"14bit","Product Function Input Variable Parameterizable":"Yes","Type Of Electrical Connection Of The Inputs And Outputs":"M12 screw-type terminals","operating voltage according to AS-Interface spezification":"26.5 ... 31.6V","Voltage supply auxiliary voltage additional for sensors Uaux":"24 ... 30V","consumed current from profile conductors of the AS-Interface at 30 V maximum":"160mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/9847c015557487a36de917f0b3a206d1.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=305310&mlfb=3RK2207-2BQ50-0AA3","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RK2207-2BQ50-0AA3/alternatives.json"},"ai":{"faq":[{"question":"What voltage ranges does it measure?","answer":"Configurable for 1... 5 V or ±10 V, with 14-bit A/D resolution.
