Powered by 24 VAC or 24 VDC, it accepts an analog control signal for precise positioning across the full stroke range. With a supply draw of 6.5 VA and an enclosure rating of NEMA 2 and IP54, this actuator is built for reliable service in mechanical rooms and air handling applications where moisture resistance and durable construction are required. Licensed HVAC technicians and controls contractors are the primary installers of this type of device.\u003c\/p\u003e\u003cp\u003eThe GMB24-SR is suited for commercial and industrial HVAC systems requiring proportional damper control. Typical applications include variable air volume systems, air handling units, and mixed-air damper assemblies where accurate airflow regulation is critical. The modulating analog input allows integration with building automation systems and DDC controllers. Its 360 in-lb torque output accommodates larger damper blades or multi-section damper frames common in commercial construction.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e360 inch-pound torque output for large or high-resistance dampers\u003c\/li\u003e\n\u003cli\u003eNon-spring return design holds last position on power loss\u003c\/li\u003e\n\u003cli\u003eAccepts analog control signal for modulating proportional control\u003c\/li\u003e\n\u003cli\u003eCompatible with 24 VAC or 24 VDC power supply\u003c\/li\u003e\n\u003cli\u003eNEMA 2 and IP54 enclosure rating for moisture-resistant installation\u003c\/li\u003e\n\u003cli\u003eLow supply draw of 6.5 VA reduces panel load\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation actuator for commercial HVAC damper assemblies requiring 24-volt modulating non-spring return control.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or controls contractor familiar with low-voltage wiring and building automation systems. Disconnect power to the control panel and damper circuit before mounting or wiring the actuator. Verify damper shaft diameter and coupler compatibility before securing the actuator to prevent mechanical binding. Follow NEC requirements for low-voltage control wiring and consult the manufacturer installation guide for analog signal wiring configuration.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: 360 in-lb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply\u003c\/strong\u003e: 24 VAC, 24 VDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Voltage Nominal\u003c\/strong\u003e: 24 VAC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupply Draw\u003c\/strong\u003e: 6.5 VA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eControl Signal\u003c\/strong\u003e: Analog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA 2, IP54\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BELIMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: GMB24-SR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BELIMO","offers":[{"title":"Default Title","offer_id":51284002603314,"sku":"GMB24-SR (SAP#104271)","price":620.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309279065.jpg?v=1781065686","url":"https:\/\/voomisupply.com\/products\/belimo-gmb24-sr-damper-actuator-360-in-lb-24v-modulating","provider":"Voomi Supply","version":"1.0","type":"link"}
