M9108 Series Information
  • Simple Direct Coupling Reduces Installation and Commissioning Time While Improving Reliability by Eliminating Damper Linkages
  • Electronic Stall Detection Ensures Higher Reliability by Deactivating the Actuator Motor When a Stall Condition Is Detected
  • Jumper‑Selectable Rotation Direction and Manual Gear Release Simplify Installation, Setup, and Field Adjustments
  • Manual Gear Release Simplifies Damper/Valve Setup and Commissioning
  • Master/Slave Operation Allows Synchronized Control for Two Actuators
  • NPT Threaded Housing Provides Easy Connection for Electrical Fittings
  • Stacked for Tandem Applications
The M91xx Series includes M9108, M9116, M9124, and M9132 models. All of these direct‑mount electric actuators operate on AC/DC 24 V power. The M91xx actuators are available for use with on/off, floating, proportional, or resistive controllers. These bidirectional actuators do not require a damper linkage, and are easily installed on a damper with a round shaft up to a 3/4 in. (20 mm) in diameter or a square shaft up to 5/8 in. (16 mm). They may be direct or remote mounted to a damper, or mounted to a valve using one of the M9000‑5xx Valve Linkage Kits. A single M91xx model delivers up to 280 lb‑in (32 N‑m) of torque. Two ‑AGx, ‑GGx, or ‑HGx models in tandem deliver twice the torque or 560 lb‑in (64 N‑m). The angle of rotation is mechanically adjustable from 0 to 90° in. 5‑degree increments. Integral auxiliary switches are available to indicate end‑stop position or to perform switching functions at any angle within the selected rotation range. Position feedback is available through switches, a potentiometer, or a DC 0(2) to 10 V signal.
