Damper Actuator, 35 in-lbs [4 Nm], Spring return, AC/DC 24 V, DC 2...10 V

For fail-safe, modulating control with minimum position setpoint, or three position control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturer’s specifications. The actuator is mounted directly to a damper shaft from 3/8” up to 1/2” in diameter by means of its universal clamp, 1/2” shaft centered at delivery. For shafts up to 3/4” use K6-1 accessory. A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft. The actuator operates in response to 24 VAC on wire 2 or 3, which allows the LF24- SR-E US to retrofit or replace Honeywell® M8405A actuators. A 2 to 10 VDC feedback signal is provided for position indication.
