Explosion Proof Electric Actuator/Damper Drive Contrac RHDE
DESCRIPTION Contrac intelligent electric rotary actuators suit continuous duty, modulating, or pulse input control applications in hazardous locations. The Contrac actuator incorporates microprocessor- based power electronics that provide remarkable positioning accuracy of the final control element. The remote mounted power electronics includes a Local Control Panel with pushbuttons, which can be conveniently located for easy access permits engineers to set up actuator travel action and performance parameters, reducing commissioning time by 50 %. The operating angles range from 30 to 270 degrees without need of additional modification. Rotary actuators are available for rated torques of between 250 Nm to 16000 Nm (80 ft-lb to 12000 ft-lb) and all share a similar design.
FEATURES • Rated torque 250Nm to 1600 Nm
• Power electronics control actuator and act as interface between unit and control system • Choice of integrated field or rack mounting options for power electronic units • Maintenance free for ten years
• Breakaway torque at end positions twice the rated torque • Adjustable mechanical stops to prevent manual over travel • Anti-coast spur wheel gear train with ball bearings • Robust, oil lubricated gearing with high mechanical efficiency. • Using ABB's Asset Vision diagnostic and engineering software tool, the actuator’s performance can be monitored online.
