With isolated power supply

Isolators convert standard input to standard output signal. In separators with an isolated power supply following circuits: input, output and power supply are separated from each other. A typical application is galvanic separation of measurement circuits installed on the plant from centrall controller. This reduces the impact of interference on control system devices such as drivers, controllers and recorders, and ensure their safety, procetcing inputs from dangers of working with remote signal sources (lightning, power line interferences, other noise sources).
