5437-672 is a NetCon Field Terminal Module manufactured and designed by Woodward as part of the 5400 Series used in Turbine Control Systems. A Field Terminal Module provides a connection point for field devices, such as sensors and actuators, in a distributed control system (DCS) or a programmable logic controller (PLC) system. It is also known as a Fieldbus Terminal or Remote I/O Module. The FTM serves as an interface between the field devices and the control system, allowing signals to be transmitted back and forth. It typically includes a set of terminals or connectors where the field device cables can be connected. The module may also contain additional circuitry for signal conditioning, isolation, and communication protocol conversion.


  • Streamlined Wiring Management: It provides a convenient and organized means of connecting and managing the wiring for field devices. Instead of dealing with lengthy cable runs back to the central control system, fieldbus protocols allow for shorter, localized wiring connections. This reduces the complexity and length of the cabling infrastructure, simplifying installation and maintenance.
  • Enhanced Reliability: The proximity of communication interfaces to field devices minimizes the potential for signal degradation or interference often associated with extended cable runs. As a result, communication between the control system and field devices remains stable and reliable, thereby bolstering the overall system performance and robustness.
  • The adoption of fieldbus protocols translates into cost savings, particularly in terms of wiring. Shorter cable runs and localized connections reduce both material and installation costs, while also simplifying cable management.
  • It's imperative to emphasize the importance of safety when working with the control system. In situations where the protected circuitry within the control system experiences a short circuit, the control system may undergo a shutdown as a protective measure.
  • This safeguard is designed to prevent further damage or potential hazards. Therefore, taking appropriate precautions to avoid short circuits and adhering to recommended safety guidelines is paramount when working with the control system and its associated circuitry. Safety should always be a top priority in industrial settings to protect both personnel and equipment.
  • The module's 37-pin configuration serves as a testament to its capacity for comprehensive connectivity. Within those pins lie the pathways to a multitude of data streams and communication channels. This intricate network of connections enables the exchange of information vital for real-time decision-making and system coordination.
  • The terminals not only simplify the installation process but also guarantee a secure and stable connection. This attention to detail not only saves time but also minimizes the risk of errors during setup and maintenance procedures.

What happens if a fault or error is detected in the input values during the voting process?

If a fault or error is detected in the input values during the voting process, the control system takes action to mitigate the issue. Typically, the erroneous value is rejected, and the correct or majority-voted value is chosen as the input for the application logic. This ensures that the control system operates based on reliable and consistent data.

How does the redundancy provided by TMR and voting improve the system's reliability?

The redundancy provided by TMR and voting improves the system's reliability by increasing fault tolerance and error detection capabilities. TMR ensures that multiple redundant channels are available for input and output handling, reducing the likelihood of single points of failure. The voting process allows the system to compare and validate the inputs, eliminating erroneous values and selecting the most reliable input for further processing.

Are there any limitations or considerations for using Specific TMR I/O Modules and FTMs?

When using Specific TMR I/O Modules and FTMs, it's important to consider factors such as system complexity, cost, and maintenance requirements. Implementing TMR and redundancy mechanisms can increase system complexity and cost due to the additional hardware and configuration needed. Regular maintenance and testing are also crucial to ensure the reliability and proper functioning of the redundant system components.
