It takes a 24 V DC control supply and uses a varistor for surge suppression — no separate suppressor needed on the coil. ## Mounting and panel fit The module is 45 mm wide, 37 mm tall, and 75 mm deep — it plugs directly onto the contactor face, so it adds no DIN-rail footprint. ## Wiring and environmental limits Rated for 690 V AC insulation at pollution degree 3, with IP20 finger-safe front protection — suitable for industrial panels where contamination is present. Operates from -25 to +60 °C, stores and ships at -40 to +80 °C, and survives 11 g shock at 15 ms and vibration 10–55 Hz at 0.35 mm.","metaTitle":"Siemens 3RA2711-1DB00 Sirius coupling module, 24 V DC","metaDescription":"Siemens 3RA2711-1DB00 Sirius coupling module for IO-Link/AS-i, reversing starter, 24 V DC, screw terminals, IP20, fits contactors S00-S3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"75mm","Solid":"0.5 ... 4 mm², 2x (0.5 ... 2.5 mm²)","Width":"45mm","title":"3RA2711-1DB00","Height":"37mm","description":"coupling module for IO-Link / AS-i, reversing start, screw terminal, can be snapped on at the front on communication-capable contactor 3RT20…-…..-0CC0","Direct Starter":"No","During Storage":"-40 ... +80°C","lifecycle_stage":"current","During Operation":"-25 ... +60°C","During Transport":"-40 ... +80°C","Fastening Method":"can be plugged into contactor","Shock Resistance":"11g / 15 ms","Bus Communication":"Yes","Mounting Position":"any","Reversing Starter":"Yes","Product Brand Name":"Sirius","Star-Delta Starter":"No","Degree Of Pollution":"3","Product Designation":"Coupling module","acc. to IEC 81346-2":"K","Vibration Resistance":"10 ... 55 Hz / 0.35 mm","Design Of The Product":"IO-Link/AS-i","acc. to DIN EN 61346-2":"K","With Core End Processing":"1x (0.5 ... 2.5 mm²), 2x (0.5 ... 1.5 mm²)","Design Of The Surge Suppressor":"Varistor","EMC immunity acc. to IEC 60947-1":"ambience A (industrial sector)","at AWG cables for auxiliary contacts":"2x (20 ... 14)","control circuit interface with IO link":"No","control supply voltage 1 at DC rated value":"24V","control circuit interface with AS-interface":"No","EMC emitted interference acc. to IEC 60947-1":"CISPR11, ambience A (industrial sector)","electrostatic discharge acc. to IEC 61000-4-2":"8 kV","field-based interference acc. to IEC 61000-4-3":"10 V/m","touch protection on the front acc. to IEC 60529":"finger-safe, for vertical contact from the front","Size Of Contactor Can Be Combined Company-Specific":"S00, S0, S2, S3","protection class IP on the front acc. to IEC 60529":"IP20","Installation Altitude At Height Above Sea Level Maximum":"2 000m","Type Of Electrical Connection For Auxiliary And Control Circuit":"screw-type terminals","insulation voltage with degree of pollution 3 at AC rated value":"690V","Product Component Removable Terminal For Auxiliary And Control Circuit":"Yes"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$55.88","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/fd82424aefe7cfb55c8635c269a631ca.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=424653&mlfb=3RA2711-1DB00"},"ai":{"faq":[{"question":"What is the 3RA2711-1DB00 used for?","answer":"It is a coupling module that provides reversing-starter logic and an IO-Link or AS-i bus interface when plugged onto a communication-capable Siemens contactor (3RT20…-…..-0CC0)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2711-1DB00","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RA2711-1DB00 when reusing this data.
