ABSTRACT:
An apparatus controls the operation of a hydrocarbon production well. The apparatus includes a supply means for providing an electric power supply. The apparatus also includes a plurality of electrically operated actuating devices. The actuating devices can be a plurality of electric motors. The apparatus includes drivers responsive to the power supply for providing a drive signal for the actuating devices. The apparatus also includes a control assembly for applying the drive signal to the actuating devices in a multiplexed manner. The power from each driver creates a power input signal. When there are more than one input signals, they are multiplexed so that a single signal is received by the actuating devices.
