Signal isolator

The signal isolator is an electrical device which is used to remove earth loop errors which are caused by noise & signal interference problems. These isolators use several electronic methods for interrupting the two grounds connections while passing an exact signal with accuracy or with a small loss.

Signal isolator gives electrical isolation among the input & output circuits. The signal can be connected through a transformer to the output. These isolators also break the straight electrical path among loop ends. They guard against hazardous calculated variable voltages & enhance protection from spikes and surges.
