M9124 Series Proportional Control
Electric Non-spring Return Actuators
The M9124-GGx and M9124-HGx Series direct-mount
electric actuators operate on 24 VAC or VDC power.
These actuators 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 or
mounted to a valve using the M9000-518 Valve
Linkage Kit.
A single M9124-GGx or M9124 HGx-2 model delivers
up to 210 lb∙in (24 N∙m) of torque. Two GGx or HGx
models in tandem deliver twice the torque or 420 lb∙in
(48 N∙m). 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 Figure 1: M9124 Series Actuator
adjustable). Position feedback is available through a
0 (2) 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
Master/Subordinate Allows synchronized control for two actuators
Operation stacked for tandem applications
Zero and Span Adjustment Allows sequential operation of dampers from
(HGx Models) a single input signal of 0 (2) to 10 VDC,
0 (4) to 20 VDC, or 0 (4) to 20 mA
