EDA-8102 Electric Damper Actuator
Proportional Control with Spring Return
The EDA-8102 Electric Damper Actuator provides
clockwise and counterclockwise proportional control of
dampers and mounts directly on the damper drive
shaft, eliminating the need for costly and complicated
linkage combinations.
The mechanically limited torque output of 100 in·lb
provides long actuator life, protection of the controlled
equipment, and minimal setup and calibration time.
The EDA-8102 Electric Damper Actuator operates on
24 VAC power. It can be ordered with clockwise or
counterclockwise return to normal.
Direct Mount
Over Torque Protection (Patent Pending)
Up to 90 Degree Clockwise or
Counterclockwise Rotation
Precise Positioning Adjustable Within Any of
the Following Input Signals: 0 to 15 VDC,
0 to 20 mA, or 135 ohm Slidewire
Coupler Fits 10 to 12 mm (0.394 to 0.472 inch)
Square or 7/16 to 1/2 inch (11 to 12.5 mm)
Round Damper Shafts
Designed to Meet 300,000 Driven Cycles
Metasys ® Network Compatible
