Hello Tom,

The implementation of ISO1450 looks good. Please make sure that the decoupling capacitors are placed as close as possible to the supply pins in the layout. I also noticed the schematic has 3 optocouplers. The ISOM8110 could be used here as well and will have an improved lifetime and flatter CTR over temperature compared to traditional light-based solutions. See Opto-emulators explained: Why you should upgrade your optocoupler technology for more details.

Best,
Andrew
