This device serves as an interface component, isolating and transmitting control signals between circuit segments through a built-in relay output stage. It is compact in form, measuring 3.228 inches long, 0.315 inches wide, and 3.858 inches tall, and weighs just 0.077 pounds. Licensed electricians and industrial controls technicians typically specify and install this component in panel builds and machine control assemblies where signal isolation and relay switching are required.\u003c\/p\u003e\n\u003cp\u003eThe 3RQ31181AB00 is suited for industrial automation environments where control signals must be coupled and switched reliably across circuit boundaries. Typical applications include PLC output interfacing, machine control panels, and process automation equipment. The relay output configuration makes it appropriate for scenarios where a dry-contact or switched output is needed downstream of a logic or low-voltage control signal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIntegrated relay output stage for signal coupling and switching\u003c\/li\u003e\n  \u003cli\u003eCompact footprint at 3.228 x 0.315 x 3.858 inches for space-constrained panel installations\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.077 pounds\u003c\/li\u003e\n  \u003cli\u003eSold individually — 1 per pack\u003c\/li\u003e\n  \u003cli\u003eProvides electrical isolation between input control signal and output relay circuit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style coupler with relay output for use in Siemens industrial control and automation panel assemblies where compatible relay coupler modules are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electrician or industrial controls technician in accordance with applicable NEC requirements and the panel or equipment manufacturer's documentation. De-energize and lock out the control panel before installing or removing this module. Verify that input signal voltage and relay output ratings are compatible with the connected circuits before restoring power. Do not exceed the rated electrical parameters of the relay output.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.228 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 3.858 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.077 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 1 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 80476621642\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3RQ31181AB00\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51383018979634,"sku":"3RQ31181AB00","price":109.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677896.jpg?v=1782585700","url":"https:\/\/voomisupply.com\/products\/siemens-3rq31181ab00-coupler-with-relay-output","provider":"Voomi Supply","version":"1.0","type":"link"}
