Zener Barriers

A Zener Barrier is a device that limits the voltage and current entering a hazardous area for use by intrinsically safe equipment. The voltage is limited or clamped by a Zener diode and the output current is limited by an output resistor, a fuse is also used in the circuit to protect the Zener diode. As per any intrinsically safety equipment, the Zener barrier allows cables to short circuit to each other or to metallic parts connected to ground without causing dangerous situations.

Kempston Controls, a leading stockist of electrical and electronic components, has a select range of Zener Barriers of all types from market leading brands such as Pepperl + Fuchs, Turck Banner, Phoenix and more, designed to suit whatever your intrinsically safe electrical installation requires.
