Belimo NMB24-MFT Rotary Actuator, 90 in-lb, Multi-Function, 24V

Description

Belimo NMB24-MFT Multi-Function Rotary Actuator Overview

The Belimo NMB24-MFT is a versatile, heavy-duty rotary actuator engineered for demanding HVAC and building automation applications. Delivering a robust 90 in-lb of torque, this multi-function actuator supports a wide range of control signal types, making it an ideal single-SKU solution for contractors and system integrators who need flexibility across diverse installations. Its 24Vac/24Vdc power supply compatibility ensures straightforward integration into virtually any commercial control panel.

Key Features

• 90 in-lb rotary torque output for reliable damper and valve actuation
• Multi-function (MFT) design supports multiple control modes in a single unit
• 4-20mA analog input with 500 Ohm input impedance
• PWM (Pulse Width Modulation) control with 1500 Ohm input impedance
• Floating point (tri-state) and On/Off control modes
• 2-10Vdc proportional control signal
• Dual-voltage power supply: 24Vac or 24Vdc
• Rotary actuator design for direct-coupled damper and rotary valve applications

Control Signal Compatibility

The NMB24-MFT’s multi-function technology eliminates the need to stock multiple actuator models. A single unit handles:

• Proportional 4-20mA signals (500 Ohm input impedance)
• PWM signals (1500 Ohm input impedance)
• Floating point (incremental) three-wire control
• Simple On/Off two-position control
• 2-10Vdc proportional voltage signals

Application Highlights

• Ideal for VAV boxes, AHUs, RTUs, and fan coil units
• Compatible with BAS/DDC systems using analog, digital, or floating point outputs
• Suitable for damper and rotary valve control in commercial HVAC systems
• Reduces inventory requirements with one actuator covering multiple control protocols
