Pepperl+Fuchs shares with you how to choose a more suitable safety barrier

There are many types of safety barriers in the market nowadays, some have been rigorously verified and some are highly imitation. How do we buy safety barriers? The first thing to determine is whether to choose a Zener safety barrier or an isolation barrier. Choose the right type to choose the brand. We recommend Pepperl+Fuchs. okplazas.com is the original German P+F Pepperl+Fuchs safety barrier. The quality is reliable and the reputation is guaranteed!

The explosion-proof principle of the P+F double plus zener grid is to use a zener diode to control the output voltage and a resistor to limit the output current. The circuit is relatively simple. When the production industry is working normally, the Zener safety barrier is equivalent to two resistors in series into the circuit, so there is no need to change the system structure. In addition, the Zener safety barrier has no influence on the accuracy of the original signal due to the transition of no signal. The isolation safety barrier uses high frequency as the fundamental wave to modulate and demodulate the signal. If the signal changes, the accuracy will be affected by the safety barrier circuit. Due to the high frequency oscillating circuit of the isolation safety barrier, radio frequency interference will be generated, which is detrimental to the system, and the isolation safety barrier is also relatively easy to damage. But the isolation safety barrier does not require intrinsically safe grounding, which is its advantage over the Zener safety barrier. In terms of market price, Zener safety barriers are also much cheaper than isolated ones. In situations where many safety barriers are needed, the price advantage of Zener safety barriers is clearly reflected. As for what kind of safety barrier is more suitable, we suggest to choose genuine products, it is best not to choose high-proof products to ensure the safe and stable use of the product.
