Belimo LMCB24-SR Actuator
The Belimo LMCB24-SR is a high-torque rotary actuator designed for precise control of dampers and valves in commercial HVACR systems. Delivering 45 in-lb (5 Nm) of torque, this proportional actuator operates on a 24VAC/DC power supply and accepts a 2 to 10 VDC control signal for modulating applications. It features a brushless DC motor controlled by an Application Specific Integrated Circuit (ASIC), which monitors and adapts motor rotation to ensure consistent stall protection and high reliability. The non-spring return design offers a selectable direction of rotation, while the universal manual override simplifies field commissioning and mechanical adjustments. With its NEMA 2 (IP54) rated housing and efficient power consumption, the LMCB24-SR is an ideal choice for VAV terminal units, small dampers, and specialized air handling equipment requiring exact positioning and long-term durability in demanding environments.
Key Benefits for Technicians:
- Precise Modulation: Responds accurately to 2-10 VDC control signals for optimized airflow and temperature regulation.
- Stall Protection: Integrated electronic technology protects the motor from burnout without the need for mechanical limit switches.
- Versatile Mounting: Includes a universal clamp for easy installation on round or square shafts, reducing truck stock requirements.
- Manual Override: External push-button allows for manual positioning during system testing or power failures.
- High Efficiency: Lower power consumption during operation reduces total transformer sizing requirements for large-scale projects.
Common Questions:
What happens if the control signal is lost on the LMCB24-SR?
This is a non-spring return actuator; it will typically remain in its last position unless the control system is configured to drive it to a specific fail-safe state before total power loss.
Can I use this actuator for on/off control?
While optimized for proportional control, it can be configured for floating or on/off control depending on the specific field wiring and controller output.
Is the rotation direction reversible?
Yes, the direction of rotation can be changed via a simple switch located on the actuator housing to match the damper's clockwise or counter-clockwise requirements.
