Johnson Controls M9109 Series Electric Non-spring Return Actuators

Electric Non-spring Return Actuators
M9109 Series

The M9109 Series direct-mount electric actuators operate on 24 VAC power and are available for use with floating or proportional controllers. These non-spring return actuators are easily installed on a Variable Air Volume (VAV) box, a round damper shaft up to 1/2 inch (13 mm) in diameter, or a 3/8 inch (10 mm) square shaft.

The M9109 models have 80 lb·in (9 N·m) running torque. They have a nominal 60-second travel time for 90° of rotation at 60 Hz (72 seconds at 50 Hz) with a load-independent rotation time. The M9109-xGC-2 models are available with integral auxiliary switches to perform switching functions at any angle within the selected rotation range.

• 35 dBA rating meets audible requirements for open ceilings
• synchronous drive provides constant rotation time independent of load
• direct shaft mount with single-screw coupler simplifies installation and provides 3-point shaft gripping
• a magnetic clutch provides torque protection for the damper and actuator
• jumper-selectable rotation direction (GGx models only) simplifies installation
• adjustable rotation stops allow application versatility with 30 to 90° clockwise or counterclockwise rotation
• 1/2 in. NPT threaded conduit opening meets electrical code requirements and allows the use of armored cable
• a manual gear release simplifies setup and field adjustments
• output position feedback (GGx models) provides simple, closed-loop control with accurate position sensing
