From the recording of the process variable to the evaluation in the control system, many errors can occur that can lead to unwanted process states. These can result in plant shutdowns or quality problems, and even pose hazards to people and the environment. In addition to faults in the device itself, isolators also monitor the connecting lines between the isolator, the field device and the control system for lead breakage or lead short circuits, depending on the device variant. In this blog post you can find out how isolated barriers from Pepperl+Fuchs detect line faults in the signal circuit without additional wiring.
