Intrinsically Safe Barriers
Intrinsically Safe Barriers
Intrinsically safe barriers are components that prevent instruments and low voltage circuits from releasing sufficient energy to ignite volatile gases in a hazardous area.

The barrier is designed to separate the control circuit from the field device. A combination of resistors, diodes and fuses work in tandem to prevent excess voltage and current from reaching the field device under fault conditions.

Intrinsically safe barriers are differentiated by voltage and current ratings, and hazardous location classification.
