Honeywell MS4609F1210/B Damper Actuator

Product Id : 285073

Honeywell MS4609F1210/B Damper Actuator is a spring-return actuator designed for the on/off control of dampers in HVAC systems. It has a torque rating of 80 lb-in (9 N•m) and a stroke of 95 degrees. The actuator is reversible, so it can be used for either clockwise or counterclockwise spring rotation. It also features two internal auxiliary switches for position indication.

Applications: HVAC systems, Smoke control systems, Fire suppression systems, Ventilation systems, Industrial control systems

Product Description

Honeywell MS4609F1210/B Damper Actuator is a high-quality, reliable damper actuator that is ideal for a variety of applications, including HVAC systems, smoke control systems, and industrial automation. It is a spring return, meaning that it will automatically return to its closed position when power is removed. This makes it ideal for use in applications where safety is a top priority.

Features of Honeywell MS4609F1210/B Damper Actuator:

  • • 30 lb-in. (3.4 N•m) or 80 lb-in. (9 N•m) minimum driving torque at 350°F (176°C).
  •  Reversible mounting facilitates use in either clockwise (cw) or counterclockwise (ccw) spring rotation.
  •  Integral spring return ensures the level of return torque.
  •  Fifteen-second spring return timing.
  •  No special cycling is required during long-term holding. (See Operation section.)
  •  No audible noise during holding.
  •  Patent pending design eliminates the need for limit switches to reduce power consumption.
  •  Models available for 24, 120, and 230 Vac.
  •  Ninety-five-degree angle of rotation.
  •  The actuator holds rated torque at a reduced power level.
  •  Die-cast aluminum housing.
  •  The housing design allows flush mounting to the damper.
  •  Designed to operate reliably in smoke control systems requiring Underwriter’s Laboratories Inc. UL555S  ratings up to 350°F.
  •  Models available with SPST position-indicating switches (7°, 85° stroke)
