The RS232 Isolator Click Board™ is a fully isolated dual transceiver Click Board™, used to provide secure and easy UART to RS232 conversion, with the galvanic isolation. The digital input and output signals are transmitted across the isolation barrier by utilizing the Analog Devices proprietary iCoupler' technology - IC scale transformer windings couple the digital signals magnetically, from one side of the barrier to the other, providing the galvanic isolation and transfer rates up to 460Kbps.
