Description
The OE281-04 Proportional Control
Damper Actuator is a shaft mounted, di-
rect coupled actuator. The Damper Ac-
tuators utilize a 24VAC/24VDC power
supply. Wiring connection to the actua-
tor is by means of screw wiring termi-
nals located on the actuator cover. The
actuator is rated for 35 in-lb of torque.
All actuators are electronically protect-
ed against overload. The angle of rota-
tion is mechanically limited to 95
.
When the end position of the actuator
or damper is reached, the actuator au-
tomatically stops. For adjustment pur-
poses, the gears can be manually dis-
engaged by pushing the manual over-
ride button on the actuator cover. A vis-
ual pointer on the actuator indicates the
position of the actuator.
Applications
The OE281-04 Damper Actuator is
used to provide control of bypass air
dampers in an Orion zoning system.
When used in zoning applications with
a bypass damper, it is wired to the air
handling unit controller boards 0-
10VDC analog output.
