Resideo m8185d1006 Rotary Actuator on Off Spring Return 60 In-lb 24V Ac Hardwired Nema 3 IP54

Product Description

The Resideo M8185D1006 is a rotary actuator designed for use with dampers and valves in commercial and industrial HVAC and building automation applications. This unit delivers 60 in-lb of rated torque and operates on 24V AC power, making it a reliable choice for controlling airflow and fluid flow in critical systems. HVAC technicians and building automation engineers rely on actuators like the M8185D1006 to precisely position dampers in air handling units, VAV boxes, rooftop units, and ventilation systems, as well as control valves in hydronic heating and cooling loops. The actuator uses an on/off control signal, meaning it moves the connected damper or valve to a fully open or fully closed position based on a simple binary command from the building automation system or controller. One of the most important features of this actuator is its spring-return mechanism. If power is lost, the spring automatically returns the damper or valve to a predetermined safe position. This fail-safe behavior is essential in life safety systems, smoke control applications, and any critical infrastructure where the damper must be in a known position during a power outage or emergency. The M8185D1006 is housed in a durable aluminum enclosure rated NEMA 3 and IP54, providing protection against dust ingress and water spray, which makes it suitable for outdoor and semi-exposed mounting locations. It is hardwired for a secure electrical connection and includes a wiring box for easier field installation. The actuator mounts via a foot mount configuration and features a double-ended square shaft measuring 3/8 inches by 3/8 inches, with a stroke rotation of 160 degrees in the clockwise direction. It closes in 60 seconds, draws 20 VA, and is rated at 20 watts. The operating temperature range spans from -40 degrees Fahrenheit to 150 degrees Fahrenheit, supporting use in demanding climates and mechanical rooms. It carries a UL Listed certification under Guide No. XAPX for use in the USA and Canada.
