The Benefits of Modules with Line Fault Transparency

Posted by Andreas Grimsehl on Tue, Nov 26, 2019

Safe Switch-On with Line Fault Transparency

Highly automated systems in sensitive areas of the process industry must ensure that pumps, valves, and active cooling systems are switched on safely at all times. All signal circuits must be monitored for possible line faults on the field side to ensure that all installed safety functions operate correctly if there is a fault. In this blog post, we explain the advantages plant operators have with using line fault transparency (LFT) modules from Pepperl+Fuchs ...

Intrinsic Safety: Isolated Barriers Bring out the Best in Protection

Posted by Patricia Stafford on Tue, Dec 22, 2015

What is intrinsic safety?

The best form of protection is prevention. So when it comes to electricity, low voltage and current flow is the way to go.

Keeping people and equipment safe is a top priority for anyone who works with electrical equipment in a hazardous area. Intrinsic safety is key. An intrinsically safe system is one in which the current and voltage are kept so low that there is not enough energy to produce arcs, sparks, flames, or explosions.

4 Types of Surge Protection Barriers—Keeping Your Signal Strong

Posted by Patricia Stafford on Thu, Jan 08, 2015

Whether you’re controlling a manufacturing process with a computer, distributed control system (DCS), programmable logic controller (PLC), or field device—surge protection barriers reduce or eliminate the risk to your equipment from lightning strikes and other harmful transient voltage or surge currents.

Below are four types of surge protection solutions, designed for a variety of applications. The common pattern you will see is that for field devices, you need to combine two different types of modules to provide protection. In contrast, a computer, DLC, or PLC requires only a surge protector.

Thinking Outside the Box with Intrinsic Safety

Posted by Robert Schosker on Thu, Sep 04, 2014

Have you or are you still thinking about taking that leap of faith to intrinsic safety? With current and voltage limited to levels below that which can cause an ignition, a 50% safety factor even under fault conditions, and the ability to wire in accordance with general purpose wiring methods, there shouldn’t be another thought. But wait. What about my field device?

In the article 'Choosing Your Intrinsic Safety Device',  by Aaron Hand, Executive Editor, Automation World, find out what you need to know about the other half of the intrinsic safety equation.

If, after reading this article, intrinsic safety sounds like something you would be interested in learning more about, we're here to help. What questions do you have?
