FD-2011D type manipulator is completed with S-series intelligent regulator. It also can be completed with KMM，KMS single circuit regulator, DZTB-2310A digital regulator. After a suitable connect, it can be used with Ⅲ-type regulator. The manipulator is installed between servo and electric actuator. When the manipulator in the automatic status, it connect servo and electric actuator; when it in the manual status, the connect will be cut and the manipulator will connect power resource with electric actuator’s positive and reverse position according to the board operating condition to control electric actuator. If you used system which formed by manipulator and regulator, there is no disturbance when you switch hand / auto status.

The manipulator adopts light-emitting diode to display the operation and display input signal by three and a half digitals.
