88 LB-IN (10 NM) SPRING RETURN
DIRECT COUPLED ACTUATORS
MS4110, MS7510, MS8110 S10 Series Spring Return Direct
Coupled Actuators (DCA) are used within heating, ventilating,
and air-conditioning (HVAC) systems. They can drive a variety
of quarter-turn, final control elements requiring spring return
fail-safe operation. Applications include:
• Volume control dampers, mounted directly to the drive
shaft or remotely (with the use of accessory hardware).
• Quarter-turn rotary valves, such as ball or butterfly valves
mounted directly to the drive shaft.
• Linear stroke globe or cage valves mounted with linkages
to provide linear actuation.
• UL (cUL) listed and CE compliant.
• All Models are plenum-rated per UL873.

MSXX10 SERIES
Spring return actuators shall be direct coupled type requiring neither crankarm
nor linkage and be capable of direct mounting to a jackshaft of up to 1.05 in.
diameter. The actuator shall connect to the shaft using a removable output hub
with a self-centering shaft coupling. This coupling shall provide concentric
mounting and include an integral adjustable range-stop mechanism.
The actuator shall provide two-position, floating, or proportional control.
Proportional control refers to direct acceptance of 0-10 Vdc, 2-10 Vdc or—with
addition of a 500 ohm resistor—a 4-20 mA input signal. Proportional and
floating control models provide a 2-10 Vdc feedback signal. Actuators shall
provide wiring terminals located within an integral access cover with conduit
connections. Proportional and floating actuators shall have a rotation direction
control switch accessible on the cover. Proportional and floating actuators
shall use a brushless DC submotor. Two-position actuators shall use a brush
DC submotor with a microprocessor control protected from overload at all
angles of rotation.
All spring return actuators must be designed for either clockwise or
counterclockwise fail-safe operation with a continuously engaged mechanical
return spring. This spring must return the actuator to a fail-safe position within
20 seconds of power loss. All actuators shall provide a means of manually
positioning the output hub in the absence of power. All actuators shall be
designed for a minimum of 50,000 full-stroke cycles at actuator rated torque
and temperature, 50,000 spring-return cycles and 1,500,000 repositions as
documented in the product literature. Run time shall be constant and
independent of: load, temperature, and supply voltage (within specifications).
All actuators shall be UL873 and cUL (CSA22.2) listed, have a five year
warranty, and be manufactured under ISO 9001 International Quality Control
Standards.
Actuators shall be as manufactured by Honeywell
