Engineered specifically for heavy-duty steam and gas turbine actuation, this card manages the critical interface between the controller and hydraulic servo valves. It excels in Triple Modular Redundancy (TMR) environments, utilizing \"median select\" voting across multiple feedback loops to eliminate single points of failure.
