MSXX10 Series
88 LB-IN (10 NM) SPRING RETURN
DIRECT COUPLED ACTUATORS
N314
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.
FEATURES
• Brushless DC submotor with electronic stall protection
for floating/modulating models.
• Brush DC submotor with electronic stall protection for
2-position models.
• Self-centering shaft adapter (shaft coupling) for wide
range of shaft sizes.
• Models available for use with two-position, single pole
single throw (spst), line- (Series 40) or low- (Series 80)
voltage controls.
• Models available for use with floating or switched
single-pole, double-throw (spdt) (Series 60) controls.
• Models available for use with proportional current or
voltage (Series 70) controls.
• Models available with combined floating/modulating
control in a single device.
• Models available with adjustable zero and span.
• Models available with line-voltage internal end switches.
• Models available with 3-foot, 18 AWG color-coded
cable.
• Access cover to facilitate connectivity.
• Metal housing with built-in mechanical end limits.
• Spring return direction field-selectable.
• Shaft position indicator and scale.
• Manual winding capability with locking function.
• UL (cUL) listed and CE compliant.
• All Models are plenum-rated per UL873.
