Johnson Control M9108 Series Proportional Electric Non Spring Return Actuators M9108-GGA-2

 

 

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
