Honeywell M9185F1002/U Modutrol actuator

The Modutrol M9185F1002/U servomotors designed to efficiently control valves or dampers in the electrical modulating circuits included in the 90 series. They are designed to provide precise and proportional control in automation systems where dynamic flow control is required.

Honeywell M9185F1002/B servos have functionality that allows them to precisely position valves or dampers in accordance with electrical signals in the modulating circuits. Their application is especially relevant in heating, ventilation, air conditioning and other technical systems where dynamic and precision process control is necessary.

The servos of this model from Honeywell provide ample opportunities for precise adjustment, which makes them an ideal choice for applications where a high degree of automation and flow control in large volumes of air or liquid is required.

Features

• Replaces the M944A, C, D; M954 engines.

• The engine and gear transmission immersed in oil ensure reliable operation and long service life.

• The mounting box provides NEMA 3 weather protection.

• The drive motor and circuit operate from 24 volts

• AC models are available with a factory-installed transformer, or an internal transformer can be added in the field.

• Adapter for screw terminals is available.

• Models with adjustable travel in the field are available (from 90° to 160°).

• The standard is a nominal time of 30 seconds for a 90° stroke and 60 seconds for a 160° stroke.

• Other time settings are available.

• The body is made of die-cast magnesium.

• Available accessories include valve and flap connections, explosion-proof housing and auxiliary switches.

• Built-in auxiliary switches are available for factory installation or can be added to TRADELINE models in the field.

• Interface modules With the possibility of adding to the C field can be installed in the mounting box to upgrade the drive to the 70 series (electronic) control.

• Timing is 4 minutes for a 160° stroke.

Gear drive: 1800

Running time: 60

Number of moves: 29164

Number of steps: 182.275

Speed: 911

Torque: 60

Controller type: Control circuit of the Honewell M9185F1002 actuator is a 90-by-135 ohm proportional controller. The control circuit can also use a 90 series high or low limit regulator with a manual minimum position potentiometer (with a total resistance of up to 500 ohms).

Motor rotation: Normally closed. The closed position is the limit of counterclockwise rotation when viewed from the engine power side. The motor opens clockwise (when viewed from the side of the power supply). The motors are supplied in the closed position.

Stroke: Fixed stroke, 90° or 160° stroke models are available. Other models are available with adjustable travel in the field from 90° to 160°. The initial position of the shaft changes when adjusting the stroke. (The midpoint of the stroke remains fixed when adjusting the stroke). The stroke

is regulated by means of cams located in the mounting block.

Load by its own weight on the shaft: Drive or auxiliary end – no more than 200 pounds [90.8 kg].

Maximum total load – 300 lbs [136.2 kg]

Rated ambient temperature:

The maximum temperature is -150° F [66° C] at 25% duty cycle.

Minimum – minus 40°F [-40°C].

Crankshaft: 3/8 inch square [9.5 mm].

Location

When installing the Modutrol M9185F1002/B servo motor, certain conditions and recommendations must be observed:

1. Avoid places with exposure to harmful substances: Do not install the device in places where acid vapors or other harmful substances may be exposed to metal parts.

2. Exclude an atmosphere with gases or vapors of explosive substances: Avoid installation in places with an atmosphere containing gases or vapors that pose an explosion hazard.

3. Coating for increased salt content: In conditions of high salt content, use a mounting base and screws coated with zinc or cadmium, not stainless steel or brass. For installation on such surfaces, it is recommended to use the 220738A adapter bracket.

4. Temperature range: Take into account the temperature conditions — the servomotors are designed to operate in the range from -40°F to 150°F [-40°C to 66°C].

5. Leave sufficient clearance for the installation of accessories: When choosing the installation location, take into account the need to leave sufficient clearance for the installation of accessories and maintenance of the engine.

6. Outdoor installation: If the device is installed outdoors, place it vertically and use sealed connectors with a mounting box that provide weather protection according to the NEMA 3 standard.

Compliance with these recommendations will ensure efficient and safe operation of the servo motor in various environmental conditions.
