Belimo LRX24-MFT Actuator

The Belimo LRX24-MFT Actuator is a high-performance, non-spring return solution designed for precise control in HVACR systems. Engineering reliability into every rotation, this 45 in-lb torque actuator utilizes Multi-Function Technology (MFT) to provide contractors with unparalleled field flexibility. Whether you are managing proportional control, floating point, or on/off applications, this unit adapts to your specific logic requirements. It natively supports a 24VAC/DC power supply and handles diverse input signals, including 4-20mA control (via 500 Ohm impedance) and PWM (Pulse Width Modulation) at 1500 Ohm. Its brushless DC motor ensures consistent running time and torque delivery, while the integrated manual override and position indicator simplify commissioning and diagnostic workflows for field technicians.

Key Benefits

• Field Programmability: Multi-Function Technology allows for onsite adjustment of control signals and running times to match specific building automation requirements.
• Versatile Signal Compatibility: Integrated impedance support for 4-20mA and PWM signals ensures seamless integration with various controllers without additional converters.
• Compact and Durable: The NEMA 2 / IP54 rated housing and small footprint make it ideal for tight retrofit spaces and plenum-rated installations.
• Reliable Operation: Electronic overload protection throughout the 0° to 90° rotation eliminates the need for end-point limit switches.

Common Questions

How do I wire the LRX24-MFT for 4-20mA control?
To utilize a 4-20mA signal, ensure the 500 Ohm input impedance is accounted for; the actuator translates this to a 2-10 VDC operating range for precise positioning.

Can this actuator be used in air plenums?
Yes, the Belimo LRX24-MFT is UL 2043 compliant, making it suitable for use in air plenums according to NEC Section 300.22(C).

What is the typical running time for this model?
The standard motor running time is 150 seconds for a 90-degree rotation, though this can be field-adjusted using Belimo PC-Tools or the ZTH handheld tool.
