Resideo Braukmann m9185d1004 24V Spring Return Foot Mounted Modutrol Actuator 150 Lb-in

Product Description

The Resideo Braukmann M9185D1004 is a 24V spring return foot mounted Modutrol motor actuator rated at 150 lb-in of torque. It is designed for proportional modulating control of dampers and valves in commercial and industrial HVAC systems. This actuator is part of the Series 90 Modutrol Motor family, which is widely used by HVAC technicians and building automation professionals who need reliable, field-adjustable control in demanding environments. The M9185D1004 operates on 24 Vac at 50 Hz or 60 Hz and consumes 20 VA while driving. It accepts a 135-ohm proportional control signal, making it compatible with Series 90 controllers used in zoning and air handling unit applications. The spring return fail-safe design ensures the actuator returns to its default position during a power loss, which is a critical safety feature for damper and valve control in ventilation and heating systems. The adjustable stroke range of 90 to 160 degrees gives installation technicians the flexibility to match the actuator to a wide range of damper and valve configurations without replacing hardware. The dual-ended shaft with a 0.375-inch square profile allows connection from either end, which simplifies installation in tight mechanical rooms or equipment enclosures. The foot-mounted design provides a stable base for heavy-duty applications, and the integral junction box delivers NEMA 3 weather protection when the motor is mounted in the upright position. Quick-connect terminals are standard, reducing wiring time in the field. Shaft deadweight load capacity is 200 lbs on either end and 300 lbs combined across both shafts. Nominal timing runs between 30 and 60 seconds. Auxiliary switches are available factory mounted or can be field added, offering additional control and monitoring options without rewiring. Transformer is not included and must be sourced separately.

• Spring return fail-safe operation returns actuator to default position on power loss, essential for damper and valve safety control
• Field-adjustable stroke from 90 to 160 degrees with dual-ended 0.375-inch square shaft for flexible installation
• NEMA 3 rated integral junction box provides weather protection for outdoor or exposed mounting locations
