Electric Non-Spring Return Actuators
M9108, M9116, M9124, and M9132 Series

The M91xx Series includes M9108, M9116, M9124 and M9132 models. All of these direct-mount line of electric actuators operate on 24 VAC or VDC 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 0 (2) to 10 VDC signal.

• six torques: 70 to 560 lb·in (8 to 64 N·m) offer the most suitable choice for the application
• four control inputs meet the needs of most applications
• output position feedback provides simple closed-loop control with accurate position sensing
• electronic stall detection ensures higher reliability by deactivating the actuator motor when a stall condition is detected
• master/slave operation allows synchronized control for two actuators stacked for tandem applications
• zero and span adjustment (HGx models) allows sequential operation of dampers from a single input signal of 0 (2) to 1 0VDC, 0 (4) to 20 VDC, or 0 (4) to 20 mA
• jumper-selectable rotation direction and manual gear release simplify installation, setup, and field adjustments
• NPT threaded housing provides easy connection for electrial fittings
