    Hi Jayalakshmi,

    Please do share more details about your input signal to make an optimum choice. It sounded like you have a field digital input coming from a sensor that needs to be isolated and given to an MCU. Please confirm if this is the use-case. Also do share as much details as possible to suggest you a suitable device.

    An example device that is meant for isolating field digital input signals is ISO1211. It doesn't read an OPEN but reads a high voltage (like 24V, 48V, 60V, etc) and 0V and provides isolated logic output to an MCU. Please do let me know if this is something similar to what you are looking for, thanks.

    Regards,
