Application
For on/off and floating point control 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. A crankarm 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 GMB(X) 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

Typical Specification
Proportional control damper actuators shall be electronic direct-coupled type,
which require no crankarm and linkage and be capable of direct mounting to a
shaft up to 1.05” diameter. Actuators must provide proportional damper control
in response to a 2 to 10 VDC or, with the addition of a 500 7 resistor, a 4 to 20
mA control input from an electronic controller or positioner. Actuators shall have
Brushless DC motor technology and be protected from overload at all angles of
rotation. Actuators shall have reversing switch and manual override on the cover.
Run time shall be constant and independent of torque. Actuators shall be cULus
listed, have a 5-year warranty, and be manufactured under ISO 9001 International
Quality Control Standards. Actuators shall be as manufactured by Belimo.
WARNING Live Electrical Components!
During installation, testing, servicing and troubleshooting of this product, it maybe
necessary to work with live electrical components. Have a qualified licensed electrician
or other individual who has been properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical safety precautions when exposed to live
electrical components could result in death or serious injury.

Actuators may be connected in parallel if not mechanically mounted to the
same shaft. Power consumption and input impedance must be observed.
Actuators may also be powered by 24 VDC.
3
Position feedback cannot be used with Triac sink controller.
4
The actuator internal common reference is not compatible.
Control signal may be pulsed from either the Hot (source)
5
or the Common (sink) 24 VAC line.
Contact closures A & B also can be triacs.
8
A & B should both be closed for triac source and open for triac sink.
For triac sink the common connection from the actuator
9
must be connected to the hot connection of the controller.

GMX24-MFT95
Proportional Control, Non-Spring Return, Direct Coupled, 24V, 0 to 135 7 Input
Torque min. 360 in-lb for control of damper surfaces up to 90 sq ft.
Application
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. A crankarm and several mounting brackets are
available for applications where the actuator cannot be direct coupled to the
damper shaft.
The default parameters for 0 to 1357 input applications of the …MFT95 actuator
are assigned during manufacturing. If necessary, custom versions of the
actuators can be ordered. The parameters can be changed by two means: pre-set
and custom configurations from Belimo or on-site configurations using the
Belimo PC-Tool software.
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 GMX 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 GMX24-MFT95 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.
