It accepts 4..20 mA or ±20 mA from 4-wire sensors via two M12 screw-type connectors, with a configurable smoothing function and 14-bit A/D resolution. The module draws power from the AS-Interface bus (26.5...31.6 V) and requires an auxiliary 24...30 V supply (Uaux) for the sensors, consuming up to 160 mA from the bus at 30 V and up to 500 mA from Uaux. ## Deployment Context — Field-Mounted Analog Acquisition With IP67 protection, this module mounts directly on the machine or conveyor — no enclosure needed for washdown or dusty environments. It fastens to standard rail or a wall using the 3RK1901-0CA00 mounting plate (ordered separately). The 60 x 152 x 29 mm footprint (W x H x D) fits the K60 compact profile; the M12 connectors face downward, keeping the cable entry clean on a DIN-rail or panel mount. Two green LEDs indicate AS-Interface communication and auxiliary power status; a red LED signals a fault — useful for a field tech walking the line. ## Selection and Sizing for the BOM This is an analog input module only — zero analog outputs (0 AO). If your application needs both AI and AO on one AS-i node, you need a different K60 variant. The 2 inputs support 2-, 3-, or 4-conductor sensors, configurable per channel (channels 1 and 2 active). The measuring range is adjustable between 4...20 mA and ±20 mA, set via the AS-i master or the module's ID code 'A' with I/O configuration '7' and profile '7.A.9'. Ensure your master supports Spec. 3.0 for A/B slave addressing. The module draws 46 mA from the bus without the auxiliary supply active, and up to 160 mA with it — factor this into your AS-i power budget, especially on longer cable runs. The mounting plate 3RK1901-0CA00 is a separate line item — don't forget it in your BOM.","metaTitle":"Siemens 3RK2207-1BQ50-0AA3 AS-Interface K60 Analog Module, 2","metaDescription":"Siemens 3RK2207-1BQ50-0AA3 AS-Interface compact module K60 analog A/B slave, 2 analog inputs for 4..20 mA / ±20 mA, 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","AS-Interface":"green LED","AUX PWR (Uaux)":"green LED","Current Signal":"Yes","During Storage":"-40 ... +85°C","Input Variable":"mA","Inputs sensors":"2/3/4-conductor sensors","Type of device":"analog input modules for current 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: 4 ... 20 mA / +-20 mA","Measuring/output value":"current","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":"$227.33","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5f847cee5982d1f5e150f8c3abcf1752.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=536515&mlfb=3RK2207-1BQ50-0AA3","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RK2207-1BQ50-0AA3/alternatives.json"},"ai":{"faq":[{"question":"What are the key electrical ratings for this module?","answer":"AS-Interface supply: 26.5...31.6 V.
