Overview Series 61 Modutrol IVâ„¢ Motors non-spring return floating control motors used with controllers that provide a switched spdt or floating output to operate dampers or valves. 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. Motors are designed for either normally open or normally closed valves and dampers.
