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