Actuador de Compuerta MS8120 – Honeywell

The MS4120F, MS4620F, MS8120F, S2024-F, and S20230-F Fast-Acting, Two-Position Actuators are spring return direct coupled actuators (DCA) for on/off damper control. The actuator accepts an on/off signal from a single-pole, singlethrow (spst)controller. Reversible mounting allows actuator to be used for either clockwise (cw) or counterclockwise (ccw)spring rotation.

The MS4120F, MS4620F, and MS8120F DCA are designed to operate reliably in smoke control systems requiring Underwriterís Laboratories Inc. UL555S ratings up to 350°F
