Belimo LM24-SR-T 24VAC/DC Modulating Damper Actuator 5Nm 2-10V Non-Spring Return

Description:

• Genuine Belimo modulating damper actuator for commercial HVAC and building automation applications
• Provides 5 Nm (45 in-lb) torque for controlling air dampers up to approximately 0.8 m² (8.6 ft²), depending on damper design
• Operates on 24 VAC/DC power with 2...10 VDC modulating control input
• 2...10 VDC position feedback output for building automation system (BAS) monitoring
• Non-spring return design holds the last commanded position during power loss
• Direct shaft mounting with adjustable rotation up to 95°
• Manual override push button simplifies commissioning and maintenance
• Selectable clockwise/counterclockwise rotation via onboard direction switch
• Maintenance-free brushless motor with constant running time independent of load
• Ideal for HVAC systems, ventilation dampers, air handling units (AHUs), VAV systems, and commercial building automation
