Isolation Interfaces
An isolation interface is a component for insulated connection and data and power transmission between devices. It is used in systems that use high-voltage, long-distance and high-accuracy communications to prevent current surges that adversely affect equipment and the body and to avoid ground loops that pick up noise. Since the insulation voltage, number of channels, supply voltage range, etc., differ depending on the product, it is necessary to select an appropriate isolation interface. Isolation methods include giant magnetoresistive GMR capable of high-speed insulation, magnetic coupling suitable for strong electric fields, capacitive coupling suitable for strong magnetic fields, and optical coupling suitable for noisy magnetic fields and electric fields. You can select from them according to the place of use and application.
