The Honeywell M9185D1004 Modutrol IV motor delivers proportional control for HVAC dampers and compatible valve applications. 

Powered by 24 VAC, this heavy-duty actuator uses a 135 Ω control signal and provides 60 lb-in. of torque for accurate positioning. 

Its spring-return mechanism automatically drives connected equipment to its normal position during power loss, supporting dependable system operation and equipment protection.

Designed for flexible installation, the M9185D1004 includes a factory-set 160-degree stroke adjustable from 90 to 160 degrees, a 30- to 60-second nominal operating time, quick-connect terminals, foot mounting, and a dual-ended 3/8-inch square shaft.

The integrated NEMA 3 enclosure helps protect the motor in demanding HVAC environments, while its -40°F to 150°F operating range supports year-round use.

For replacement applications, Honeywell M9185D1004, Honeywell Q7230A1005 and Honeywell 50017460-003 together directly replace the M7285Q1008 Damper Actuator and must be purchased separately to form a complete replacement.
