    Hi Bogey,

    Device ISO7760 would not be able to accept 32V DC directly hence cannot be directly used with 32V input or output. We do have an isolator that is specifically designed to work with upto 60V field digital inputs. Please have a look at ISO1211 (single channel) and ISO1212 (two channels). Like the opto coupler the device ISO121x doesn't need a separate power supply on the field side and is going to work with the field inputs directly. For more details, please refer to ISO121x product page at the link below.

    For digital outputs, you can use ISO77xx to isolate the channels followed by digital output drivers like DRV devices or ULN. For the non-isolated digital output driver device suggestions, you can post your question in Motor Drive forum at the link below.
