Modutrol IV Motors
M6285 Floating Modutrol IV™ Motors, for Slaving Applications only
Series 62 Modutrol IV™ Motors are 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 and can be used
for slaving Series 90 motors or rebalancing an external control
circuit.
• Integral junction box provides NEMA 3 weather protection if motor is
mounted in the upright position
• Integral spring return returns motor to normal position in the event of
power failure
• 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
• Spring return motors can operate valve linkages from power end
or auxiliary end shafts for normally closed or normally open valve
applications
• 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
• Include electrically isolated feedback potentiometer that provides
shaft position indication
