GMB24-SR | Belimo Modulating Damper Actuator 360 In Lb 24V Non Fail Safe

Belimo · Motors & Motion

Description  The Belimo GMB24-SR is a high-torque non fail-safe damper actuator designed to deliver 360 in-lb (40 Nm) for precise modulating airflow control. It operates on AC/DC 24 V power and supports a 2–10 V control signal with integrated position feedback for accurate damper positioning.     Technical Specifications  Condition New/Never Used Surplus Brand Belimo Category Actuators & Dampers Part Number GMB24-SR Subcategory Damper Actuators Nominal Voltage AC/DC 24 V Nominal Frequency 50/60 Hz Voltage Range AC 19.2…28.8 V / DC 21.6…28.8 V Power Consumption (Operation) 4.5 W Power Consumption (Rest) 2 W Transformer Sizing 6.5 VA Control Signal 2…10 V (4…20 mA with resistor) Input Impedance 100 kΩ (2…10 V), 500 Ω (4…20 mA) Position Feedback 2…10 V Torque Output 360 in-lb (40 Nm) Angle of Rotation Max. 95°, adjustable Running Time (Motor) 150 s / 90° Electrical Connection 18 AWG plenum cable, 1/2" NPT Degree of Protection IP54 / NEMA 2 Noise Level 45 dB(A) Ambient Temperature -30…50°C Weight 3.9 lb (1.8 kg)   Information About GMB24-SR The GMB24-SR is part of Belimo’s GMB series of non fail-safe damper actuators engineered for reliable modulating control in commercial HVAC systems. It features electronic overload protection throughout the full 0–95° rotation range to protect internal components and ensure consistent torque output. The actuator supports 2…10 V control and can be adapted for 4…20 mA operation using an external resistor, allowing compatibility with a wide range of building automation systems. A compact housing, selectable motor direction, and external manual override push button simplify installation, commissioning, and service. Key Features Non Fail-Safe Operation: Provides powered damper positioning without spring return, suitable for applications where fail-safe action is not required. High Torque Output: Delivers a constant 360 in-lb (40 Nm) torque to reliably drive medium and large air dampers under varying load conditions. Modulating Control Capability: Accepts a 2…10 V control signal with optional 4…20 mA configuration for precise proportional airflow regulation. Electronic Overload Protection: Actively protects the actuator across the entire rotation range to prevent damage from obstruction or excessive load. Integrated Position Feedback: Supplies a 2…10 V feedback signal for continuous damper position monitoring and closed-loop control. Selectable Direction Of Motion: Motor rotation direction can be configured via an onboard switch to accommodate different mounting orientations. Manual Override Function: External push button allows manual positioning during setup, testing, or maintenance without tools. The GMB24-SR delivers the reliability and precision required for accurate modulating airflow control in non fail-safe HVAC damper applications.
