Honeywell MS8109F1010 Fast Acting, Two-Position Spring Return Actuator (CW & CCW, 24V, 80 lb-in)
Description
Honeywell’s Fast-Acting, Two-Position Actuators are line volt (24V), 80 lb-in., spring return direct coupled actuators (DCA) for Fire and Smoke dampers (on/off control). The actuator accepts an on/off signal from a single-pole, single-throw (SPST) controller. Reversible mounting allows actuator to be used for either clockwise (cw) or counterclockwise (ccw) spring rotation
