Fault Insertion Unit (FIU) Information

Are you working on some Fault Insertion Testing? Pickering Interfaces was the first PXI vendor to introduce switching systems designed specifically to address Fault Insertion (FI) testing applications. We have the widest range of PXI Fault Insertion products of any vendor to meet your requirements, ranging from small systems to the largest systems.

Fault Insertion units (FIU) allow users to insert common faults into systems, like shorts and opens, that might occur on real life control systems. The controllers in these systems need to work in a responsible way to ensure they do not take unintended actions, for example shutting down engines simply because a sensor has failed. Automated Fault Insertion units are particularly useful where systems may need to verifying at regular intervals, for example as the result of design or firmware changes. They allow tests to be run in a controlled way, one that can be verified without the human element involved in manual FI systems and patch panels. It is simple to verify that nothing has changed that might for example to be detrimental to passengers in a transport system.
