M9102-AGA-2S, -3S and M9104-xGA-2S, -3S Series Electric Non-Spring-Return
Actuators
Description
The M9102 and M9104 Series Actuators are
direct-mount, non-spring-return electric
actuators that operate on AC 24 V power.
These synchronous motor-driven actuators
provide floating control (AGA), floating control
with automatic shutoff (IGA), and proportional
control with selectable 0-10 or 2-10 VDC
(GGA). The -2S models are equipped with
plenum cables, and the -3S models are
equipped with terminal blocks.
All models are compact in size and are easily
installed on VAV boxes, Variable Volume and
Temperature (VVT) two-position zone
applications, or small- to medium-sized
dampers with a round shaft up to 1/2 in.
(13 mm) in diameter or a 3/8 in. (10 mm)
square shaft.
The M9102 Series Electric Non-Spring-Return
Actuators provide a running torque of
18 lb·in (2 N·m), and the nominal travel time is
30 seconds at 60 Hz (36 seconds at 50 Hz) for
90° of rotation. The M9104 Series Electric
Non-Spring-Return Actuators provide a
running torque of 35 lb·in (4 N·m), and the
nominal travel time is 60 seconds at 60 Hz
(72 seconds at 50 Hz) for 90° of rotation.
Refer to the M9102-AGA-2S, -3S and
M9104-xGA-2S, -3S Series Electric
Non-Spring-Return Actuators Product Bulletin
(LIT-1201742) for important product
application information.
Features
• Two Torques Available: 18 and 35 lb·in
(2 and 4 N·m) — offer the most suitable
choice for the specific application.
• Short 30-Second Travel Time Available —
provides a quick response for two-position
zone applications.
• 35 dBA Nominal Audible Noise Rating —
meets the audible noise requirements for
open-ceiling environments.
• Synchronous Drive — provides a constant
rotation time that is independent of the
load.
• 100,000 Cycle Rating — provides years of
trouble-free service.
• Direct Shaft Mounting with Single-Screw
Coupler — reduces installation time and
provides three-point shaft gripping.
• Magnetic Clutch — protects the actuator
gear train and the damper from damage
due to excessive torque during a stall
condition.
• Manual Gear Release — simplifies
actuator setup and adjustments in the field.
• Plenum Cable or Screw Terminal Electric
Connections — make wiring quick and
easy.
• Floating, Floating with Timeout, and
Proportional 0(2) to 10 VDC Control Inputs
Available — offer a full range of control
input options.
• Small, Compact Design — allows
installation in tight-fitting locations.
Applications
The M9102 and M9104 Series Electric
Non-Spring-Return Actuators are designed to
position balancing, control, round, and zone
dampers in HVAC systems. These electric
actuators are also designed to position blades
in a VAV box, or they can be used in VVT
two-position zone applications.
Each actuator mounts directly to the surface in
any convenient orientation using a single
No. 10 self-drilling sheet metal screw
(included with the actuator). No additional
linkages or couplers are required. Electrical
connections on the actuator are clearly labeled
to simplify installation.
Repair Information
If the M9102 or M9104 Series Electric Actuator
fails to operate within its specifications,
replace the unit. For a replacement actuator,
contact the nearest Johnson Controls®
representative.
