Intrinsic Safety Barriers

Intrinsic safety barriers 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 Interface Technology Product Selection Guide

Pepperl+Fuchs Isolated Barriers

Isolated Barriers

Galvanic isolation to protect measurement and control circuits from signal distortion and dangerous surges. Also convert, standardize, and split measurement and control signals.

Pepperl+Fuchs 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.
