FAQs:
  • What types of input signals does the FBM214 module support?
    The FBM214 supports any combination of standard 4 to 20 mA analog input signals and HART digital FSK signals superimposed on the 4-20 mA current loop, providing flexibility for various field instrumentation.
  • How does the FBM214 handle communication with HART field devices?
    As a HART communications host, the FBM214 allows the I/A Series system to request and receive up to two digital messages per second from each HART field device using universal, common practice, and device-specific commands via the Intelligent Field Device Configurator (IFDC).
  • What is required when using an external power supply for multiple channels?
    When powering two or more channels from a common external supply, a Cable Balun module is required to prevent channel cross talk and ensure accurate, reliable signal transmission across all inputs.
  • In which industrial environments is the FBM214 module suitable?
    The FBM214 is designed for rugged use in Class G3 harsh environments, making it ideal for applications in oil and gas, petrochemical, power generation, water and wastewater, and pharmaceutical or food processing plants.
