                    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
