SYSTEMS, DEVICES, AND METHODS FOR PROVIDING CONTROL SIGNALS
摘要
Certain exemplary embodiments comprise a system, comprising: an electrical isolator adapted to couple a processor of a programmable logic controller to a user load; a transistor adapted to provide switching of a control signal provided by the processor for the user load; a totem pole output coupling the electrical isolator and the transistor and adapted to switch a gate of the transistor; and a power supply adapted to provide a floating regulated DC voltage to the gate of the transistor.
