EMI - Throwing the flag on Interference

In the Controls Industry, Electromagnetic Interference (EMI) is a big deal.  Control System cables and equipment running all over production facilities creates antennas, electric fields and cross communication.   EMI can have a significant negative impact on control signals in various ways. EMI can introduce noise into control signals, leading to distortion. This distortion can alter the original signal's amplitude, frequency, or phase, causing the control system to receive incorrect or incomplete information.  Control signals are often low voltage and sensitive to external interference. When EMI disrupts these signals, it can degrade the signal integrity, leading to data errors or loss of critical information.  EMI can induce spurious signals or noise pulses that are misinterpreted by the control system as valid signals. This can lead to false triggers, where the system responds to non-existent commands, causing unintended actions or even system shutdowns.  Many control systems use digital communication protocols to transmit signals. EMI can interfere with the timing and synchronization of these protocols, leading to data packet loss, communication errors, or even complete communication breakdowns.

To mitigate the negative impacts of EMI on control signals, it’s essential to implement proper shielding, grounding, and filtering techniques.  American Electrical, Inc.(AEI) sells a cable grip made by AGRO, that implements an easy way to ground cable shields and eliminate EMI in controls systems.  The product is called Easyconnect and makes a fast, secure, permanent connection of your cable shields to the body of the Nickel Plated Brass cable grip - ensuring cable shield ground integrity (provided your control cabinet is properly grounded).  Also elimination of EMI in your control system !  Call us at 804.379.2899 to learn more or click on the link below:

Additionally, some other best practices are: using fiber optic cables and systems, using twisted-pair cables, maintaining adequate separation between power and signal lines, and ensuring good cable management can help reduce the susceptibility of control signals to EMI.
