SM24A-MP - Belimo Damper actuator 20 Nm, 150 s adjustable, 95° AC / DC 24 V with MP-Bus

At IACS we provide Free Delivery and Next 1-2 day Delivery for all the Belimo Actuators in stock.

The Belimo SM24A-MP is an Actuator used in HVAC systems and applications to manage dampers.

This type of Actuator applies a Rotary motion to regulate the damper.

The Torque force applied by the SM24A-MP is 20 Nm.

The power supply requested for this Rotary Actuator is 24Vac/Vdc.

IACS has the best prices on the right Belimo Actuators for your system.

Features
 

• Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with an anti-rotation strap to prevent the actuator from rotating.


• Manual override Manual operation is possible with the pushbutton (the gearing latch remains disengaged as long as the pushbutton is pressed or detented).
  
  
• Adjustable angle of rotation  Adjustable angle of rotation with mechanical end stops.
  


• Mode of operation The actuator is controlled with a MP-BUS signal
• Parameterisable actuators The factory settings cover the most common applications. The output signal and other parameters can be altered with the MFT-H parameterising device or the BELIMO Service Tool, MFT-P.


• Home position When the supply voltage is switched on for the first time, i.e. at commissioning or after pressing the «gear disengagement» switch, the actuator travels to the home position.
  The actuator then moves into the position defined by the control signal.
  
  
• High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.
