DFI302

DFI302 is a key-interfacing element in the distributed architecture of field control systems. It combines powerful communication features with direct I/O access and advanced control for discrete and continuous applications. Due to its modular structure, it can be placed inside panels in the control room or sealed boxes in field. Highly expandable, it is targeted to applications ranging from small standalone systems to large and complex plants.

O DFI302 is a modular multifunctional device with a DIN-rail mounted backplane into which all components are installed, including main and fieldbus power supplies (DF50 and DF52, respectively), controllers (DF63, DF73, DF95 and DF97), and line impedance (DF53) modules. They are plugged-in through industrial grade connectors and by using a robust metal screw. A conventional I/O subsystem with modules for analog and discrete inputs and outputs can be connected (optional). Modularity is the keyword for DFI302 flexibility. Besides, since all modules including the fieldbus power supply subsystem are plugged into the same backplane, the DFI302 comes up as a single integrated unit.
