SYSTEM, METHODS, AND APPARATUS FOR PROVIDING REDUNDANT POWER CONTROL USING A DIGITAL OUTPUT MODULE

摘要

A method for providing redundant power control to a load using a digital output module includes coupling at least one sourcing driver to a voltage supply and Io a first output terminal, coupling at least one sinking driver to a voltage return and to a second output terminal, and coupling a load to the first output terminal and to the second output terminal The method also includes sensing a failure in one of the at least one sourcing driver and the at least one sinking driver.
