Belimo LMB24-10P-HM Actuator

The Belimo LMB24-10P-HM provides high-torque performance for commercial VAV applications, delivering 45 in-lb of torque with precise on/off or floating point control. Operating on a versatile 24VAC/DC power supply, this rotary actuator is specifically designed for integration with VAV-10K potentiometer feedback systems, ensuring accurate damper positioning and reliable airflow regulation. The "HM" hardware mounting configuration facilitates rapid installation on standard damper shafts, reducing field labor for contractors. Its brushless DC motor technology is microprocessor-controlled, offering consistent run times and avoiding the burn-out risks associated with older synchronous motors. This rotary damper actuator is built for longevity in demanding HVAC environments, maintaining high performance across a wide range of static pressures. Professionals choose the LMB24-10P-HM for its seamless compatibility with BAS protocols and its robust mechanical construction, making it an essential component for system retrofits and new installations alike.

• High Torque Output: Delivers 45 in-lb (5 Nm) for positive closure on medium-sized VAV boxes and dampers.
• Versatile Power Compatibility: Supports 24V AC/DC inputs, simplifying field wiring and inventory management.
• Precise Feedback: Integrated VAV-10K potentiometer allows for exact position tracking within the control loop.
• Efficient Installation: Streamlined hardware mounting (HM) design ensures compatibility with standard 1/2-inch to 1.05-inch round shafts.
• Maintenance-Free Operation: Brushless motor design eliminates the need for limit switches and reduces mechanical wear.

How do I wire the Belimo LMB24-10P-HM for floating point control?
Standard wiring involves connecting terminal 1 for common, terminal 2 for hot, and pulsing terminals 3 and 4 to drive the actuator clockwise or counter-clockwise according to the controller's demand.

Is the feedback potentiometer adjustable?
The VAV-10K potentiometer provides a fixed 10k ohm range relative to the actuator's rotation, typically used to provide physical position confirmation back to the VAV controller.

Can this actuator be used in outdoor applications?
The unit is NEMA 2 rated; if installation in exposed environments is required, a protective NEMA 4X weather shield must be utilized to prevent moisture ingress.
