Functional Description

5437-523 is an Analog Field Terminal Module developed by Woodward. It supports multiple analog input and output channels, allowing for flexible connectivity with sensors, transducers, actuators, and other analog devices commonly used in industrial applications. Integration of Analog FTM into the control system is made seamless through its compatibility with Woodward's MicroNet control platform. It supports communication protocols that enable smooth data exchange with other system components, such as PLCs (Programmable Logic Controllers), SCADA (Supervisory Control and Data Acquisition) systems, and DCS (Distributed Control Systems).


  • The TMR (Triple Modular Redundant) Field Termination Module (FTM) plays a crucial role in the control system by combining the analog output signals from all three kernels into a single signal at the FTM's terminal blocks. This consolidation of signals simplifies the wiring and connectivity process, allowing for a more streamlined and efficient installation.
  • To ensure compatibility and adaptability to different interfaced circuits, the FTM incorporates field selectable jumpers. These jumpers are located on the system FTMs and provide the flexibility to configure the latent fault detection logic for each output. The latent fault detection logic is responsible for detecting any faults or abnormalities in the output signals. By selecting the appropriate jumper settings, the control system can adapt the latent fault detection logic to match the specific circuitry being interfaced with the FTM.
  • The field selectable jumpers offer customization options to align the control system with the characteristics and requirements of the external circuits. By configuring the latent fault detection logic accordingly, the system can optimize fault detection and ensure compatibility with various devices or systems connected to the FTM.
  • The inclusion of field selectable jumpers enhances the versatility and adaptability of the FTM, enabling seamless integration with a wide range of external circuits. It allows for precise and tailored configuration, ensuring that the control system effectively monitors and detects faults in the output signals. The ability to customize the latent fault detection logic through the use of field selectable jumpers ensures the compatibility and reliability of the control system when interfacing with different external devices or circuits.
  • Equipped with standard screw clamp terminals and a 37-pin connector. This module is designed to provide precise analog signal handling capabilities, making it a valuable component in industrial control and automation systems. Its standard screw clamp terminals facilitate secure and efficient connections, while the 37-pin connector offers versatility in wiring configurations, making it an essential asset for various industrial applications.
