Direct Coupled Damper Actuator—Spring Return
S10 Series: MS4110; MS7510; MS8110
Spring Return Direct Coupled Actuator, 88 lb-in
MS4110, MS7510, and MS8110 Spring Return Direct Coupled
Actuators (DCA) are used within heating, ventilating, and airconditioning (HVAC) systems. They can drive a variety of quarterturn, final control elements requiring spring return fail-safe
operation.
• 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 three-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.
