Series 71 Modutrol IV Motors are non-spring return motors used to control dampers and valves. These motors accept a voltage signal from an electronic controller, allowing them to position a damper or valve at any point between fully open and fully closed.
Features
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 field adjustable stroke (90 to 160 degrees).
Integral auxiliary switches are available factory mounted, or can be field 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.
