ISO7721: ISO 485

Part Number: ISO7721
Other Parts Discussed in Thread: ISO1410

Hi Sir 

UART to RS485 schematic as below 

May I know ISO7721 could be replace below opto or not ?

  • Kai,

    Yes it looks like the ISO7721 would work just fine to replace just the optos. However, have you considered using the ISO1410 to replace both the optos and the transceiver? This would allow you to have isolated RS485 all in one device.

    Respectfully,
