Servo motor Honeywell MS8120B1006

Honeywell MS8120B1006 actuator is part of a professional series of electric actuators used in HVAC systems. It is a spring return type, ensuring the mechanism returns to a safe position upon power loss. This solution is typically used for smoke and fire dampers, as well as burner air dampers where automatic closure in emergencies is important. Technical specifications (for MS8120 series): Depending on the modification, parameters of model MS8120B1006 may vary, but based on the marking, key properties can be determined: Torque: Usually about 10 Nm, suitable for medium-sized dampers. Supply voltage: Standard for this type of actuator is 24 V AC/DC (low voltage control) or 230 V AC depending on factory specification for a specific index. Spring return time: Ensures rapid damper closure upon power loss (typically less than 25 seconds for 90°). Control: Supports 2-position (open/close) or 3-position (floating) control. Some versions support modulation via 0-10 V or 4-20 mA signal. Key advantages: Safety function: The spring return is a key advantage, as upon emergency power loss or fire safety system activation, the damper automatically closes, preventing fire spread or gas leakage. Smooth operation: The actuator design ensures smooth and quiet damper movement, extending the service life of both the actuator and the damper mechanism. Built-in limit switches: Allow precise adjustment of rotation angles (0–90°) without the need for additional components.
