Information About MS7520H2208
The MS7520H2208 is a Honeywell direct-coupled actuator with spring-return fail-safe operation. It is designed for quarter-turn dampers, ball valves, butterfly valves, cage valves, and globe valves. The actuator provides 175 lb-in of torque and a nominal 90-second operating time, with a 95° maximum rotational stroke. It also provides 2–10 VDC feedback and two adjustable auxiliary switches for position indication or control.
Key Features:
- 175 lb-in Torque: Provides approximately 20 Nm of torque for damper and valve positioning.
- Spring Return: Returns the controlled device to a fail-safe position when power is removed.
- Floating/Proportional Control: Supports floating-point and 2–10 VDC control signals.
- 24 VAC/VDC Operation: Designed for 24 VAC or 24 VDC power.
- 95° Rotation: Provides up to 95° of rotational travel for quarter-turn applications.
- Two Auxiliary Switches: Includes two internal SPDT auxiliary switches for position signaling.
- Direct Coupling: Mounts directly to compatible damper and valve shafts.
- Wide Shaft Compatibility: Supports round shafts from 3/8 to 1.06 inches and square shafts from 3/8 to 11/16 inches.
The MS7520H2208 delivers the control and positioning functions required for HVAC damper and valve applications.
