Modutrol IV™ Series 2 Motors
M7284, M7285 & M7294

Series 72 Modutrol IV Motors are spring return and non-spring return motors (per motor type) 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.

• 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.
• 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°).
• Integral auxiliary switches are available factory mounted, or can be field 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.
• Models available with adjustable start (zero) and span.
