261557, Pepperl + Fuchs 2 Channel Zener Barrier, ATEX

รายละเอียดสินค้า / Product Details

**P&F Dual Channel Zener Diode Barriers**
Using a dual channel barrier impedes a direct grounding of the intrinsically safe circuit. The ground is only made in the event of a failure, if the zener diodes conduct. This circuit also suppresses influences of external circuits.
Typical application – thermocouples

**Certificate No.**
BAS 01 ATEX 7005

****
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.
