Foundation Fieldbus Universal Bridge DFI302
DFI302
Foundation Fieldbus Universal Bridge

The DFI302 is a powerful multifunction hardware component integral to the modular SYSTEM302 that includes all the best-of-breed hardware and software you need to manage, monitor, control, maintain and operate your plant. The DFI302 throughout the plant is completely self contained and performs most of the functions required by a system and very few additional components are therefore required.

  • Integral part of SYSTEM302
  • Single integrated unit of interface, linking device, bridge, controller, gateway, Fieldbus power supply and distributed I/O subsystem.
  • Tight integration with intelligent devices and software from multiple manufacturers due to use of open standards as FOUNDATIONTM Fieldbus and OPC.
  • Connects to existing equipment through conventional I/O and Modbus communication.
  • Full redundancy and fault isolation for high safety and uninterrupted operation
  • Leanest and most cost effective architecture.
  • High information throughput from plant floor throughout the enterprise.
