Honeywell Modutrol IV Servo Motor

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.

 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 the 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 an 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 aluminium 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.

• Models available with adjustable start (zero) and span.

• Models available with 4 to 20 mA input signal.

• Models available with 2 to 10 Vdc input signal.

Voltage, Nonadjustable: 2 to 10 Vdc.

Input Impedance:

4 to 20 mA Input: 100 ohms.

2 to 10 Vdc Input: 400K ohms. 

Stroke: Most models available with field adjustable strokes from 90° to 160°. Stroke adjusted by means of potentiometers located in the wiring compartment.

Timing: Nominal 30 seconds for 90° stroke and 60 seconds for 160° stroke.

Dead Weight Load On Shaft: 200 lb (91 kg) on motor power or auxiliary end; a maximum combined load of 300 lb (136 kg).

Ambient Temperature Ratings: -40 to 150°F (-40 to 66°C).

Shaft: 3/8 in. (9.5 mm) square.

Motor Rotation:
