Webinterface isolated using an optocoupler circuit and an equivalent circuit using ISO6721 , TI's digital isolator solution targeted for cost-sensitive applications. A UART interface is commonly configured with a standard diode input and open collector output optocoupler. Additional circuitry is needed with optocouplers, which adds board space and WebPhotocoupler-isolated input (current source output-compatible type and negative common type) This is the input circuit with the anode side of the photocoupler as the input terminal. This input is used to receive output signals from such sources as source-type transistor outputs and relay switches.
