Pepperl + Fuchs 1 Channel Zener Barrier, ATEX

P&F Single Channel Zener Diode Barriers

Zener barriers provide cost saving Ex-protection for various applications in process automation systems. The amount of energy transferred to the hazardous location is limited to a safe level incapable of igniting the explosive atmosphere.

Isolation Barriers

Pepperl+Fuchs shunt zener diode barriers are for use as safety interfaces between intrinsically safe and non-intrinsically safe circuits. They are manufactured from Makrolon® and designed to conduct electrical signals - in either direction - between safe and hazardous areas and to limit the amount of energy which can be transferred from a safe to a hazardous area in the event of fault conditions occurring in the safe area.
