Analog Inputs and Outputs
Analog Inputs and Outputs in the Mark V system are integral to the monitoring and control of various aspects, particularly in the context of turbines. Here's an in-depth expansion of these features:
Analog Inputs
- Transducer Sources: Most of the analog inputs in the Mark V system originate directly from transducers on the turbine. These transducers include sensors for parameters such as vibration and speed. These inputs play a crucial role in providing real-time data for monitoring and control.
- Current Inputs: In addition to transducer-specific inputs, the Mark V system also accommodates 4-20 mA and 0-1 mA inputs for other types of transducers. These options broaden the range of transducers that can be used with the system.
- Excitation Power: Each analog input has the capability to receive isolated 21 V dc excitation power for the connected transducer. This power supply ensures that the transducers receive the necessary voltage to operate effectively and provide accurate data.
- Jumper Configurations: The system offers flexibility through the use of jumpers, allowing users to select various parameters. These selections can include choosing between current or voltage input, specifying the size of the burden resistor, and configuring grounding options.
- Versatility: Some inputs can be switched between voltage and current input modes by simply selecting the appropriate jumper configuration. This versatility allows the system to adapt to a wide range of transducer types and requirements.
- Current Input Mode: In the current input mode, a burden resistor transforms the transducer current into a voltage signal. This voltage is then parallel-wired internally to the R, S, and T controllers. In Simplex applications, it's connected to just R. Any discrepancies between the inputs from the three controllers are flagged as an internal diagnostic fault. Despite this, the control and protection system continues normal operations based on the median signal, ensuring the system's reliability.
- Range Monitoring: Additional diagnostics actively monitor the inputs to ensure they are within their proper range. This helps maintain the accuracy and integrity of the data provided by the analog inputs.
Analog Outputs
- Current Output Options: The Mark V system provides both 4-20 mA (with a 500 ohm maximum burden) and 0-200 mA (with a 40 ohm maximum burden) analog current outputs. These outputs serve the purpose of driving remote instrumentation for monitoring and control purposes.
- Configuration Flexibility: These analog outputs can be independently configured from the Mark V operator interface, allowing users to tailor their settings to specific instrumentation and monitoring requirements.
- Mark V system's Analog Inputs and Outputs are vital components in the monitoring and control of turbines and related systems. They offer a wide range of flexibility through jumper configurations, enabling the system to accommodate various types of transducers and instrumentation. The system's diagnostic features ensure data accuracy and reliability, while the analog outputs provide the means to interface with remote instrumentation for comprehensive monitoring and control.
