Abstract
The specification discloses a two-directional switched driver for use either independently or in a method of controlling production processes and apparatus therefor. The driver, whether used independently or in a process controller, utilizes polarity signals and a retriggerable timer to produce separate forward and reverse output signals which may be used to drive reversible motors or two-directional actuators by way of standard switching techniques. Examples of such uses are the use of most any reversible motor, or two-directional actuators to control mechanical, pneumatic or hydraulic circuits, such actuators operated by the driver may be rotational or non-rotational in nature.
