Series 62 Modutrol IV™ Motors Spring Return and Non-Spring
Return oating control motors are used with controllers that
provide a switched SPDT or oating output to operate dampers
or valves. These motors also have an internal electrically isolated
feedback potentiometer that provides indication of the motor shaft
position.
• 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
• Motors are designed for either normally open or normally closed
valves and dampers
• -F models have an internal electrically isolated feedback
potentiometer that provides indication of the motor shaft position
