Intrinsic Safety Barriers

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. This simplifies maintenance and repair of Ex i circuits.

Pepperl+Fuchs offers a variety of intrinsic safety barriers for different requirements. Select between isolated barriers and Zener barriers that ensure safe signal transmission in hazardous areas.

Isolated Barriers
  • Isolated Barriers

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.

Zener barriers
  • Zener Barriers

Zener barriers prevent the transmission of excessively high energy levels from the non-explosion hazardous area to the hazardous area. These interface modules are the right choice when galvanic isolation is not needed or otherwise provided.
