Honeywell M4185B1009 Modutrol Motor

Aluminum Cased modular motor with Honeywell labelDescription

The Honeywell M4185B1009 Modutrol IV motor is a 2-position, spring-return actuator designed for reliable operation of dampers or valves. This motor is engineered to ensure that the controlled element returns to its starting position during power failures or interruptions, enhancing system safety and reliability.

Included with the motor is a transformer, which simplifies installation and integration into existing systems. The M4185B1009 is part of the Series 41 and Series 81 Modutrol IV motors, known for their robust construction and dependable performance in both line- and low-voltage applications.

This actuator is ideal for applications requiring precise control and fail-safe operation, such as HVAC systems, industrial processes, and commercial building automation. Its spring-return mechanism ensures a default position, which is critical for maintaining system integrity and safety during unexpected power losses. The Honeywell M4185B1009 is a trusted choice for demanding environments that require consistent and reliable damper or valve control.

Features

  • Fixed torque throughout the entire voltage range.
  • Integral spring return returns motor to normal position when power is interrupted.
  • Integral junction box provides NEMA 3 weather protection if motor is mounted in the upright position.
  • 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 degrees).
  • Motors are designed for either normally open or normally closed valves and dampers.
  • Integral auxiliary switches are available factory mounted, or can be field added.
  • Motors can operate valve linkages from the 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).
