Non-Spring Return Direct Coupled Actuator - Honeywell VRN Series Manual

Non-Spring Return Direct Coupled
Actuator
APPLICATION
This non-spring return direct-coupled damper actuator
provides modulating and floating/2-position control for:
air dampers, air handlers, ventilation flaps, louvers, and
reliable control for air damper applications with up to 10
sq. ft./ 44lb.-in. (5 Nm) and 20 sq. ft./88 lb.-in. (10 Nm)
(seal-less damper blades; air friction-dependent).
FEATURES:
• Declutch for manual adjustment
• Adjustable mechanical end limits
• Access cover includes enclosed screw terminal strip
(22 to 14 AWG) for electrical connections
• Models available with 3 foot 18 AWG color-coded
cable
• Mountable in any orientation
• Function selection switch for selecting modulating or
floating/2-position control
