General

The M7281, M7282, M7284, M7285 and M7294 are Electronic Modutrol® Motors used to control dampers and valves. These motors accept a current signal from an electronic controller to position a damper or valve at any position between open and closed..

Features

• Replace M744S,T,Y and M745S,T,Y Motors.
• M7284, M7281 are 150 lb.-in. non-spring return; M7294 is 300 lb.-in. non-spring return; M7285, M7282 are 60 lb-in. spring return.
• Oil immersed motor and gear train for reliable performance and long life.
• Wiring box provides NEMA 3 weather protection.
• Quick-connect terminals standard—screw terminal adapter available.
• Adapter bracket for matching shaft height of older motors is standard with replacement motors.
• Die cast aluminum housing.
• Models available with integral auxiliary switches.
• Models available with adjustable zero and span..

Specifications

• Make: Honeywell
• Model : M6294F1009-F/U
• Honeywell Modutrol IV servo motors
• Modutrol IV Motors are spring return and non-spring return motors used to control dampers and valves.
• M62xx models are three-wire floating control motors for use with controllers that provide a switched spdt or floating output and have an internal electrically
• isolated feedback potentiometer that provides indication of the motor shaft position.
• M72xx models accept a current or voltage signal from an electronic controller to position the motor shaft to any point between open and closed.
• M91xx and M94xx models use a 135Ohm modulating proportional signal to position the motor shaft to any point between open and closed.
• Modutrol IV motors are used for damper and valve control in industrial burner applications and air handling installations.
• Approvals: CE, UL, FM, CSA, EAC
• Protection class: IP44
• Weather protection kit is available as accessory to upgrade to IP54
• Ambient temperature: -40...66C
• Maximum humidity: 85%rh
• Features: Screw terminals are standard.
• Adapter bracket for matching shaft height of older motors (ModIII) is available.
• Most models have field adjustable stroke (90 to 160).
• Die-cast aluminium housing.
• Two adjustable internal SPDT auxiliary switches are factory mounted.
• Dual shaft ends for normally open or normally closed valve or damper application. Both shaft ends offer the same torque rating.
• Modutrol motor timings are independant of line frequency.
• Torque ratings for dual-ended shaft motors are the sum of the shaft torques (power-end torque plus auxiliary-end torque).
• Breakaway torque is the maximum torque available to overcome occasional large loads such as a seized damper or valve.
• The breakaway torque is 1.5x the normal rated torque.
• Other models than listed in this catalogue are available outside Europe.
• Most models can be replaced by the available European models.
