A vibratory system for a vibration feeder includes pulse means for generating electrical digital pulse signals. A controller controllably converts the electrical digital pulse signals either into an incrementally increasing or decreasing DC voltage level. At least one vibration block is coupled to the controller for being increased or decreased in its amplitude of vibration in response to the respective incrementally increasing or decreasing DC voltage level generated by the controller. A remotely located additional controller, such as a programmable logic controller, may be coupled to the controller for transmitting electrical digital pulse signals to control the amplitude of vibration.
