M7685 Modutrol IV™ Motor
Proportional, spring-return motors for use with Honeywell W7080
panel 14-17 Vdc output; with minimum position adjustment.
• Integral spring return returns motor to normal position in the event of
power failure
• Integral junction box provides NEMA 3 weather protection
• Motor and circuitry operate from 24 Vac
• Quick-connect terminals are standard
• 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
