NMX24-LON
LonWorks
®
, Non-Spring Return, 24 V
Torque min. 90 in-lb for control of damper surfaces up to 22 sq ft.
Application
Direct coupled actuators for direct link to LonWorks network. Actuators are easily
installed by direct shaft mounting on air dampers in ventilation and air conditioning
systems. Actuator can be controlled by any compatible LON controller or automation
system.
For proportional modulation of dampers in HVAC systems. Actuator sizing should be
done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper shaft up to 1.05" in diameter by means
of its universal clamp, 1/2” self centered default. A crank arm and several mounting
brackets are available for applications where the actuator cannot be direct coupled to
the damper shaft.
Operation
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.
The NMX24-LON series provides 95° of rotation and a visual indicator indicates
position of the actuator. When reaching the damper or actuator end position, the
actuator automatically stops. The gears can be manually disengaged with a button on
the actuator cover.
The NMX24-LON actuators use a brushless DC motor, which is controlled by an
Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent
damage to the actuator in a stall condition. Power consumption is reduced in holding
mode.
Add-on auxiliary switches or feedback potentiometers are easily fastened directly onto
the actuator body for signaling and switching functions.
