Foundation Fieldbus Control Transmitter - ATEX/IEC

Discrete position control and precision, non-contact position feedback with digital communication via FOUNDATION Fieldbus protocol in a simple, integrated package. With options for linear or rotary control valves and remote PST and ESD initiation.

Features & Benefits:

  • Microprocessor based technology allows digital communication via FOUNDATION Fieldbus protocol.
  • Remote and local partial stroke test (PST) and emergency shut down (ESD) initiated remotely via FOUNDATION Fieldbus signal for safety system applications.
  • Optional external button to initiate partial stroke test.
  • Valve position measurement via a non-contact magnetic pick-up eliminates mechanical drive arms or linkages increasing reliability in high cycle applications or where vibration is present.
  • Highly visible position indicator.
  • Models F430 and F431 feature corrosion-resistant resin enclosure.
  • Models F450 and F451 feature heavy duty 316 stainless steel enclosure.
