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.
