M9208-xxx-x Series Electric Spring-Return Actuators
Description
The M9208-xxx-x Series Electric
Spring-Return Actuators provide control of
dampers in HVAC systems. All actuators in
this series provide 70 lb·in (8 N·m) rated
torque. A mechanical spring-return system
provides rated torque with and without power
applied to the actuator. The series includes
the following control options:
On/Off, 24 V, 120 VAC, 230 VAC power
On/Off and Floating Point, 24 V power
Proportional, 24 V power, for 0(2) to
10 VDC or 0(4) to 20 mA Control Signal
These actuators are configured for direct
mounting and do not require a damper
linkage. Actuators can be mounted directly to
a damper shaft from 5/16 to 5/8 in.
(8 to 16 mm) diameter with a universal clamp.
For shafts up to 3/4 in. (19 mm) diameter, use
the accessory Large Shaft Coupler Kit
M9208-600. An accessory crankarm and
remote mounting kit are available for
applications where the actuator cannot be
direct coupled to the damper shaft. Optional
line voltage auxiliary switches indicate an
end-stop position or perform switching
functions within the selected rotation range.
Refer to the M9208-xxx-x Series Electric
Spring-Return Actuators Product Bulletin
(LIT-12011480) for important product
application information.
