M9108, M9116, M9124, and M9132 Series Electric Non-Spring-Return Actuators
Description
The M91xx Series includes M9108, M9116,
M9124, and M9132 models. All of these
direct-mount electric actuators operate on
AC/DC 24 V power. The M91xx actuators are
available for use with on/off, floating,
proportional, or resistive controllers. These
bidirectional actuators do not require a damper
linkage, and are easily installed on a damper
with a round shaft up to a 3/4 in. (20 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 one of the M9000-5xx Valve Linkage
Kits.
A single M91xx model delivers up to 280 lb·in
(32 N·m) of torque. Two -AGx, -GGx, or -HGx
models in tandem deliver twice the torque or
560 lb·in (64 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.
Position feedback is available through
switches, a potentiometer, or a DC 0(2) to
10 V signal.
Features
simple direct coupling reduces installation
and commissioning time while improving
reliability by eliminating damper linkages
six torques: 70 to 560 lb·in (8 to 64 N·m)
offer the most suitable choice for the
application
four control inputs meet the needs of most
applications
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/slave operation allows
synchronized control for two actuators
stacked for tandem applications
zero and span adjustment (-HGx models)
allows sequential operation of dampers
from a single input signal of DC 0(2) to
10 V, DC 0(4) to 20 V, or DC 0(4) to 20 mA
jumper-selectable rotation direction and
manual gear release simplify installation,
setup, and field adjustments
NPT threaded housing provides easy
connection for electrical fittings
manual gear release simplifies
damper/valve setup and commissioning
Applications
M91xx actuators are designed to position air
dampers and valves in HVAC systems.
Applications include: positioning return air or
exhaust dampers, controlling face and bypass
dampers, positioning blades for variable
volume fans, positioning VF4000 and
VF5000 Series butterfly valves, and
positioning VG1000 Series ball valves and
VG7000 Series globe valves when used with
the M9000-5xx Series Valve Linkages. Two of
the following models provide twice the amount
of running torque of a single unit when
mounted in tandem: M9116-GGx or -HGx,
M9124-AGx, -GGx or -HGx, and M9132-AGx
or -GGx.
Refer to the manufacturer’s information to
properly size the damper, valve, and/or
actuator. Spring-return actuators, such as the
M9206 and M9216 Series actuators, are
recommended for use with outdoor air
dampers in cold climates. These compact
M91xx actuators use a DC motor with stall
detection circuitry that operates throughout
the entire stroke.
The -GGx, -HGx, and -JGx models employ
noise-filtering techniques on the control signal
to eliminate repositioning due to line noise.
Rotation is mechanically limited to 93° by
integral end stops. The position of the actuator
is visually indicated from 0 to 90° on the cover.
An anti-rotation bracket prevents lateral
movement of the actuator. Pressing the
spring-loaded gear release on the actuator
cover disengages the gear train for manual
repositioning of the coupler.
