M9108 Series Proportional Electric

Non-spring Return Actuators

The M9108-GGx-2 and M9108-HGx-2 Series

direct-mount electric actuators operate on 24 VAC or

VDC power, and are available for use with proportional

controllers. These bidirectional actuators do not

require a damper linkage, and are easily installed on a

damper with a round shaft up to 3/4 in. (19 mm) in

diameter or a square shaft up to 5/8 in. (16 mm). They

may be direct- or remote-mounted to a damper.

A single M9108-GGx-2 or M9108-HGx-2 model

delivers up to 70 lb∙in (8 N∙m) of torque. 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. Jumpers on the actuator allow users to

select the direction of action, range of control input,

and calibration (fixed or adjustable). Position feedback

is available through switches, a potentiometer, or a

0 to 10 VDC signal.

Features and Benefits

 Two 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 if a stall condition is detected

 Dual Scale (0 to 90° and

90 to 0°) on the Cover

Indicates the position of the actuator’s rotation

in 10° increments

 Removable Coupler Allows adjustment of the rotation range from

0 to 90°

 Steel U-bolt Clamp Provides four-point damper shaft gripping

 Jumper-selectable Rotation

Direction and Manual Gear

Release

Simplifies installation, setup, and field

adjustments

 National Pipe Thread (NPT)

Threaded Housing

Provides easy connection for electrical fittings
