Belimo AMCB24-MFT Actuator

The Belimo AMCB24-MFT Actuator is a high-torque, non-spring return damper actuator engineered for precise proportional modulation in commercial HVAC systems. Delivering 180 in-lb of torque, this unit is the direct replacement for the AMCX24-MFT series, where "X" denotes customizable factory settings. Utilizing Multi-Function Technology (MFT), this actuator provides a 2-10 VDC control signal and can be field-configured for 4-20 mA operation with a 500 ? resistor. This versatility allows technicians to adapt the unit to various modulating control requirements without swapping hardware. The brushless DC motor is controlled by an application-specific integrated circuit (ASIC), which protects against overload and provides digital rotation sensing to stop the motor automatically if a stall condition occurs. With a constant 35-second run time independent of load and a universal clamp for shafts up to 1.05", it ensures reliable performance even on large damper surfaces up to 35 sq ft.

• High Torque Output: Provides 180 in-lb [20 Nm] of force suitable for large dampers and high-pressure HVAC applications.
• Flexible Signal Input: Supports 2-10 VDC and 4-20 mA control inputs out of the box for seamless integration with modern BMS controllers.
• Electronic Overload Protection: Eliminates the need for limit switches by electronically monitoring rotation to prevent motor burnout.
• Manual Override: Features an external push button to disengage the gear train for manual adjustment during commissioning or maintenance.
• MFT Programmability: Allows for on-site adjustments of control signal, feedback, and running time using the Belimo PC-Tool.

Can the AMCB24-MFT replace an older AMCX24-MFT model?
Yes, the AMCB24-MFT is the official direct replacement. The "B" indicates the basic model, which covers the standard technical requirements of the "X" customizable version in most field applications.

What is the maximum shaft size this actuator can mount to?
The unit features a universal clamp designed to direct-couple to damper shafts ranging from 1/2" to 1.05" in diameter.

Does this actuator require a specific transformer?
For proper 24 V AC/DC power supply, ensure transformer sizing accounts for a 26 VA load (Class 2 power source) per actuator.
