PURPOSE:To provide the controller reducing the number of wirings with the improved transmission signal, decreasing the wiring cost, able to resist the noise, and requiring the reduced space in wiring when the signal of an encoder and the signal of a peripheral sensor are transmitted to the controller. CONSTITUTION:The controller is provided with an encoder 2 having a rotation detecting section 2a outputting the mechanical rotation angle of a body to be controlled as a prescribed electric signal and a conversion circuit 2b converting the electric signal from the rotation detecting section 2a into a digital signal and a sensor 3 detecting the physical state of the body to be controlled. The conversion circuit 2b converts an electric signal from the sensor 3 into a digital signal at its output, and a signal transfer processing circuit 2c is provided to multiply the digital signal from the conversion circuit 2b by the digital signal from an encoder 3 at its output to a controller 4. The power can be applied from the controller 4 to the encoder 3 and from the encoder 2 to the sensor 3. |
