Series 71, 72, and 76
Modutrol IV™ Motors
APPLICATION
The Series 71, 72 and 76 Modutrol IV Motors are spring return
and non-spring return motors used to control dampers and
valves. The motors accept a current or voltage signal from an
electronic controller to position a damper or valve at any point
between open and closed.
FEATURES
• Replaces M734H,J,; M744S,T,Y; and M745L,S,T,Y
Motors.
• M7164, M7261, M7284, and M7294 are non-spring
return motors; M7282, M7285, M7286 and M7685 are
spring return motors.
• Integral spring return returns motor to normal position
when power is interrupted.
• Integral junction box provides NEMA 3 weather
protection.
• Motor and circuitry operate from 24 Vac. Models
available with factory installed transformer, or a field
added internal transformer.
• Quick-connect terminals are standard—screw terminal
adapter is available.
• Adapter bracket for matching shaft height of older
motors is available.
• Most motors have field adjustable stroke (90° to 160°).
• Die-cast aluminum housing.
• Integral auxiliary switches are available factory
mounted, or can be field added.
• Nominal timing standard of 30 seconds (90° stroke),
and 60 seconds (160° stroke). Other timings available.
• 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.
