Here are some key features and specifications of the Honeywell M9484F1057 actuator:

Control Signal: The M9484F1057 actuator operates on a 24V AC/DC control signal. It is commonly used with Honeywell's T7300 or T7350 series thermostats or other compatible HVAC control systems.

Modulating Control: This actuator provides modulating control, meaning it can adjust the position of a damper or valve in response to a varying input signal. This allows for precise control of airflow or fluid flow based on the desired temperature or pressure setpoints.

Non-Spring Return: The M9484F1057 actuator is a non-spring return type, which means that it does not have a built-in mechanical spring to return the actuator to a specified position in the event of a power loss. Instead, it relies on the HVAC control system to maintain the desired actuator position.

Manual Override: The actuator is equipped with a manual override feature that allows for manual operation of the damper or valve in case of a power failure or for maintenance purposes. The manual override lever or knob is typically located on the actuator itself.

Torque Rating: The M9484F1057 actuator has a torque rating of 135 lb-in (15.3 Nm), which indicates the maximum torque it can deliver to move dampers or valves in HVAC applications.

Mounting: It features a direct-coupled mounting for easy installation on dampers or valves with a standard

shaft diameter.
