Information About M4185A1001
The M4185A1001 is part of Honeywell’s Modutrol IV Series, known for precise and durable electric motors used in damper and valve control applications. This model features an integral spring return mechanism that automatically repositions the motor to its normal position when power is interrupted, providing a fail-safe function in HVAC systems. The M4185A1001 delivers a uniform torque of 60 lb-in throughout its entire voltage range, ensuring consistent performance. Its dual-ended square shaft design allows flexible mounting for either normally open or normally closed valve configurations. With an adjustable stroke between 90° and 160° and optional auxiliary switches for added control versatility, this motor offers exceptional adaptability in both new and retrofit applications. Its rugged NEMA 3-rated construction and integrated transformer ensure reliable operation even in demanding environments.
Key Features:
- Spring Return Fail-Safe: Automatically returns to normal position when power is lost for system protection.
- Two-Position SPST Control: Provides simple open/close actuation for dampers and valves.
- Adjustable Stroke Range: Field-adjustable from 90° to 160° for flexible control requirements.
- Constant Torque Output: Maintains 60 lb-in torque across full operating voltage range for precise movement.
- Dual-Ended Shaft Design: Enables operation from either end for normally open or closed valve linkages.
- Rugged NEMA 3 Housing: Provides weather-resistant protection when installed upright.
- Auxiliary Switch Options: Factory-mounted or field-installable switches enhance control customization.
- Wide Operating Temperature Range: Functions reliably between -40°F and +150°F for year-round operation.
- Integrated Transformer: Simplifies installation and ensures stable electrical performance.
- Quick-Connect Terminals: Speeds up wiring and reduces installation time.
The M4185A1001 delivers the reliability and precision required for industrial and commercial HVAC systems, ensuring safe operation, efficient air and fluid control, and long-term durability.
