Compact, robust safety zener barriers any application.
Zener barriers connect intrinsically safe and non-intrinsically safe circuits, such as Ex i field devices with automation systems. Whether it's for standard signals such as 4 to 20 mA or for less common signals, you can trust us to find you the right solution. R. STAHL will be happy to help you choose the right solution from our comprehensive range.
You can find useful information about safety barriers in our overview and selection guide. Alongside a general introduction, they also provide you with detailed examples for illustration purposes – everything you need to take the hassle out of choosing the ideal safety barrier.
The design of R. STAHL's single-channel and dual-channel zener barriers features a high robustness combined with a low footprint – as a result, not only do they take up very little space, but you can also expect an impressively long service life. What is more, they are easy to install. All you need to do is snap them onto the DIN rail, this action having the added advantage that it establishes the required potential equalization. A standardised back-up fuse that can be used in any model simplifies storage and maintenance.
Our experienced support team are ready to help you choose the best zener barrier for your needs, decide whether equipment can be classified as simple apparatus and generate an assessment report.
