High voltage differentials in industrial automation systems can create havoc without the proper application of galvanic isolation techniques

The connection of multiple systems in industrial automation applications provides many benefits, but when there are high voltage differences between these systems, designers need to manage voltage inconsistencies. These include large differences in system grounds. The hardware techniques that tackle these analog and digital galvanic isolation challenges have optic, magnetic, and capacitive barriers. The types of isolation transmission signals include analog signals, power, and digital signals.  http://bit.ly/2HXUbSw
