The Woodward 5501-470 is a LinkNet Splitter Module specifically designed for use with Woodward 505 and 505E digital governors. This essential component facilitates the expansion of communication networks within turbine control systems. It allows a single 505/505E controller to communicate with multiple devices, such as operator control panels (OCPs), other controllers, or monitoring systems, over the proprietary LinkNet serial communication network. By providing one input and four output ports, the 5501-470 module acts as a hub, ensuring reliable and efficient data distribution. This module is critical for creating more complex and integrated control architectures, enhancing the monitoring and operational capabilities of steam turbines and other industrial prime movers.
