9905-970 is a LinkNet 6-Channel Input Module manufactured and designed by Woodward as part of the 9900 Series used in Turbine Control Systems. The Linknet 6 Channel Input Module's primary function is to provide the control system with up to six analog input signals, which can be used to monitor various parameters in the turbine system. These input signals could come from sensors that measure things like temperature, pressure, or flow rate, for example. By monitoring these parameters, the control system can make adjustments to the operation of the turbine to optimize its performance and ensure safe and efficient operation.


  • Multiple input channels: Provides up to six input channels, which allows for the monitoring of multiple parameters simultaneously.
    Analog input signals: The module accepts analog input signals, which are commonly used in turbine control systems to monitor parameters like temperature, pressure, and flow rate.
  • High accuracy: Designed to provide highly accurate measurements of input signals, which is essential for maintaining safe and efficient turbine operation.
  • Wide input range: Supports a wide range of input signals, including signals with voltages ranging from 0-10V and currents ranging from 0-20mA.
  • Scalability: Can be used in conjunction with other Linknet components to create a scalable control system that can be customized to meet the needs of different turbine applications.
  • Easy installation: Easy to install and configure, thanks to its plug-and-play design and user-friendly interface.

What should be done if all of a chassis have Fault LEDs on during normal control operation?

If during normal control operations have Fault LEDs on, it is recommended to check the kernel's CPU module for a failure. The CPU module may be causing the issue, and further investigation or replacement may be necessary.

What should be done if only the Fault LED is on or flashing during normal control operation?

If during normal control operation only the Fault LED is on or flashing, the first step is to ensure that the module is installed in the correct slot. If it is installed correctly and the fault persists, the module should be replaced.

What action should be taken when a module fault is detected?

When a module fault is detected, it is important to disable or de-energize its outputs. This helps prevent any potential issues or malfunctions caused by the faulty module.
