Description
The Rolls-Royce Marine LIAAEN Helitron DC0016A (Part No: UL0303711) is a specialized I/O controller module integral to the LIAAEN/Helitron propulsion control and pitch management systems. This controller is designed to bridge the gap between shipboard bridge command inputs and the hydraulic actuator systems responsible for Controllable Pitch Propeller (CPP) settings. It manages the conversion of electrical command signals into precise hydraulic positioning, ensuring that the vessel’s propulsion output remains responsive and stable across varied operating conditions.
