Information About MS7520A2007
The MS7520A2007 is part of Honeywell’s MSXX20 series of direct-coupled actuators. Its self-centering shaft adapter secures the actuator to a compatible damper shaft. Mounting orientation determines the spring-return direction, while a switch selects the powered opening direction. A manual crank provides positioning capability during installation and servicing.
Key Features:
- Multiple Control Modes: Supports floating, proportional, and two-position operation.
- Modulating Input: Accepts 0–10 VDC or 2–10 VDC control signals.
- Current Signal Compatibility: Supports 4–20 mA control when used with a 500-ohm resistor.
- Output Torque: Provides 175 lb-in (20 N·m) for driving compatible dampers.
- Spring Return: Mechanically returns the actuator when supply power is removed.
- Self-Centering Coupling: Clamps directly onto a compatible damper shaft.
- Adjustable Travel: Provides a 95° ±3° stroke with mechanical adjustment in 5° increments.
- Manual Positioning: Includes a manual crank for positioning without powered operation.
The MS7520A2007 delivers the reliability and precision required for controlled damper positioning and spring-return operation in HVAC systems.
