PEPPERL+FUCHS KFD2-STC4-EX2, P/N: 42083
The primary function of this module is to safely supply power to 2-wire SMART transmitters operating in hazardous explosive environments (such as Zone 0, 1, 2 or Div 1, 2). It intercepts the incoming 0/4 mA to 20 mA analog field loop signal, isolates it completely via galvanic barriers, and transfers it securely to the safe control area (such as a PLC or DCS).
