Modutrol IV Motors
M7164 Modutrol IV™ Motors
Series 71 Modutrol IV™ Motors non-spring return motors are used
to control dampers and valves. These motors accept a voltage
signal from an electronic controller to position a damper or valve
at any point between open and closed.
• Integral junction box provides NEMA 3 weather protection if motor is
mounted in the upright position
• Motor and circuitry operate from 24 Vac
• Quick-connect terminals are standard – screw terminal adapter is
available
• Adapter bracket for matching shaft height of older motors is available
• Motors have eld adjustable stroke (90 to 160 degrees)
• Integral auxiliary switches are available factory mounted, or can be
eld added
• All models have dual shafts (slotted and tapped on both ends)
• All models have auxiliary switch cams
• Fixed torque throughout the entire voltage range
