The Group 11E rotary control drive is certified for applications in Class 1 Division 1 locations which present an ignition or explosion risk. Beck Group 11 drives are used for automatic modulation of dampers, quarter-turn valves and other final control elements which require fine, responsive control. The Group 11E extends the company’s product line to environments and applications which can now benefit from the precise control Beck products are known for, such as power generation, pulp/paper and many other industries.

The design allows for precise control, with low current draw and no duty-cycle limitations. The on-board control module feeds the drive’s motor windings directly, completely eliminating external motor starters and controls. The drive does not coast or overshoot, and will not overheat even under continuous modulation. The control module includes many features and functions such as variable speed operation, communications capabilities and diagnostics.
