M9124-JGx-2 Series 3-Wire Resistive
Electric Non-spring Return Actuators
The M9124-JGx-2 Series direct-mount electric Figure 1: M9124 Series Actuator
actuators operate on 24 VAC or VDC power, and are
available for use with resistive 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 or mounted to
a valve using the M9000-518 Valve Linkage Kit.
A single M9124-JGx-2 model delivers up to 210 lb·in
(24 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.
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 when a stall condition is
detected
Removable Coupler Allows adjustment of the rotation range from
0 to 90°
Steel U-bolt Clamp Provides four-point damper shaft gripping
Master/Subordinate Allows synchronized control for two actuators
Operation stacked for tandem applications
Jumper-selectable Rotation Simplify installation, setup, and field
Direction and Manual Gear adjustments
Release
Noise-filter Eliminates repositioning due to line noise
National Pipe Thread (NPT) Provides easy connection for electrical fittings
Threaded Housing
