KCD2-RR2-Ex1.SP P+F Resistance Repeater Pepperl Fuchs Intrinsic Safety Barriers

Intrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres.

In addition to their explosion protection function, isolated barriers offer galvanic isolation to protect measurement and control circuits from signal distortion and dangerous surges. These interface modules also convert, standardize, and split measurement and control signals.

  It transfers resistance values of RTDs or potentiometers from hazardous areas to safe areas.
  A 2-, 3-, or 4-wire technique is available depending on the required accuracy.
  The input card of the control system measures the same load as if it were connected directly to the resistance in a hazardous area.
