M9108-JGx-2 Series 3-Wire Resistive Electric
Non-spring Return Actuators
The M9108-JGx-2 Series direct-mount electric
actuators operate on 24 VAC or VDC power, and are
available for use with resistive input 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-JGx-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. A jumper on the actuator allows users to select
the direction of action. Position feedback is available
through a 0 to 10 VDC signal. Figure 1: M9108 Series Actuator
Features and Benefits
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 Indicates the position of the actuator’s rotation in 10°
90 to 0°) on the Cover increments
Removable Coupler Allows adjustment of the rotation range from 0 to 90°
Steel U-bolt Clamp Provides four-point damper shaft gripping
Coupled to a Ball-style Regulates the flow of hot or chilled water, 50% glycol
Valve with Linkage solution, and low pressure steam
Jumper-selectable Rotation Simplifies installation, setup, and field adjustments
Direction and Manual Gear
Release
Noise Filter Eliminates repositioning due to line noise
National Pipe Thread (NPT) Provides easy connection for electrical fittings
Threaded Housing
