Information About M4185B1009

The M4185B1009 is part of Honeywell’s Modutrol IV Series, a robust line of industrial and HVAC control motors built for precise, long-lasting performance. This model provides spring-return operation, ensuring automatic repositioning to normal state upon power interruption for fail-safe reliability. It includes a built-in transformer, dual-ended shaft, and one auxiliary switch for enhanced versatility. The adjustable stroke feature (90° to 160°) allows for customized control settings, while its 60 lb-in torque rating and 20 VA drive power make it suitable for a wide range of damper and valve control applications. Designed with a rugged steel housing and weather-protected junction box, it withstands harsh environmental conditions and continuous operation demands.

Key Features

  • Spring Return Function: Returns the motor to its normal position automatically during power loss, ensuring system safety.
  • High Torque Output: Provides 60 lb-in of torque for reliable control of dampers and valves under heavy loads.
  • Adjustable Stroke Range: Field-adjustable from 90° to 160° for flexible operation in various system configurations.
  • Dual-Ended Shaft Design: Enables operation of valve linkages from either end for normally open or normally closed configurations.
  • Integrated Transformer: Simplifies installation by providing built-in power conversion for Modutrol IV control circuitry.
  • Durable Construction: Features a rolled steel frame and aluminum flange for extended service life in industrial environments.
  • Auxiliary Switch Included: One factory-mounted SPDT switch allows additional control or feedback circuit integration.
  • Weather Protection: NEMA 3-rated junction box (upright mount) ensures protection against dust and moisture.

The M4185B1009 delivers the reliability and precision required for HVAC control applications, offering smooth actuation, configurable performance, and long-term operational durability.
