M9104-AGx-2N Electric Non-Spring-Return Actuators

Description

The M9104-AGA-2N synchronous
motor-driven actuator provides floating
(three-wire) control and is easily installed on a
VAV box or a small- to medium-sized damper
with a round shaft up to 1/2 in. (13 mm) in

diameter or a 3/8 in. (10 mm) square shaft.
This compact, non-spring-return actuator has
a 35 lb·in (4 N·m) running torque and 40 lb·in
(4.5 N·m) minimum stall torque in a compact,
easy-to-install package. It has a nominal
90-second travel time for 90° of rotation at
60 Hz (108 seconds at 50 Hz) for 90° of
rotation.

The M9104-AGS-2N Actuator/Transmitter
combines an M9104-AGA-2N with a pre-wired
DPT-2015 Differential Pressure Transmitter
that has a 0 to 1.5 in. water column (W.C.)
(0 to 374 Pa) differential pressure range.

Non-Spring-Return Actuators Product Bulletin
(LIT-2681121) for important product

application information.

Features

• 30 dBA rating meets audible noise
requirements for open ceilings

• synchronous drive provides constant
rotation time that is independent of load

• 100,000 cycle rating extends actuator life
due to improved technology

• direct shaft mount with single-screw
coupler simplifies installation and provides
3-point shaft gripping

• magnetic clutch provides torque protection
for the actuator gear train and damper

• adjustable rotation stops allow application
versatility with 30 to 90° clockwise (CW) or
counterclockwise (CCW) rotation

• manual gear release simplifies setup and
field adjustments

• screw terminal connection makes wiring
easy

Applications

The M9104-AGx-2N actuator is used to
position balancing, control, round, and zone
dampers in typical HVAC applications. It is
also used to position the blades in a VAV box.

The actuator mounts directly to the surface of
a VAV box, round damper, or small
rectangular damper with a single No. 10
self-drilling sheet metal screw (included).
There are no additional linkages or couplers
required. Clearly labeled electrical terminals
simplify installation. Refer to the damper or
VAV box manufacturer’s information to select
the proper timing for the actuator.

When combined with a VAV controller, the
actuator provides reliable, integrated damper
control. Refer to the M9104-AGx-2N Series
