[FAQ] How can Functional Isolators correct ground shifts and improve noise tolerance on a signal line?

Ground loop interference is created when two or more devices in the same circuit have different ground potentials with respect to one another. Ground loop interference and shifting grounds can cause a variety of issues such as errors in data transmission or signal loss.

Functional isolators can be used to break the ground loop increase signal integrity and decrease errors in data transmission

• Basic and reinforced isolation also prevent risk of electrical shock to people or damage to equipment in addition to increasing signal integrity and preventing errors

The image below shows how functional isolators can be placed between two different devices and provide increased signal integrity:

GPD = Ground Potential Difference

GND = Ground
