Belimo LMB24-MFT : Non Fail-Safe Damper Actuator, 35 in-lb Torque, 24VAC/DC, Programmable (2-10VDC Default) Control Signal, 5-Year Warranty
The Belimo LMB24-MFT is a basic non-fail-safe multifunction technology actuator designed for controlling dampers in typical commercial HVAC applications. It operates with a torque motor of 45 in-lb [5 Nm] and has a nominal voltage of AC/DC 24 V. The control is MFT/programmable, and it provides position feedback in the range of 2 to 10 V.
Features:
- Suitable for proportional modulation of dampers in HVAC systems.
- Direct mounting to a damper shaft from 1/4" up to 5/8" in diameter.
- Universal clamp accommodates shafts up to 3/4" diameter
- Default parameters for 2-10 V applications are assigned during manufacturing.
- Actuator is electronically protected against overload and does not require limit switches.
- Provides 95° of rotation with a visual position indicator.
- Brushless DC motor controlled by an Application Specific Integrated Circuit (ASIC).
- Power consumption reduced in holding mode.
Typical Specification:
- Proportional control damper actuator with brushless DC motor technology.
- Actuators shall be cULus listed, have a 5-year warranty, and be manufactured under ISO 9001.
- Suitable for use in air plenums per NEC and IMC regulations.
The actuator can be configured on-site using the Belimo PC-Tool software, and custom versions are available if needed. It is a reliable and versatile solution for HVAC damper control applications.
