Part Number: ISO7231M
Other Parts Discussed in Thread: ISO7731

The ISO7231 datasheet states that the part is approved according to EN61010-1, but not to which level.

Which working voltages is the part approved for? for  basic insulation? Reinforced insulation?

BR,

    Hi Lars,

    Thanks for reaching out.
    Section 9.3.3 of ISO7231M datasheet provides details related the certifications. As you can see in the image below, the device only supports basic isolation.

    ISO7231M is one of our older generation devices, we recommend you to use our latest generation of devices that offer much better performance. ISO77xx offers reinforced isolation for various channel configurations and is also available with various package options. ISO7731 is going to be pin-compatible to ISO7231M, hence I recommend you to use ISO7731.

    Let me know if you have any other questions, thank you.

    Regards,

    Hi Koteshwar,

    Thank you for answering.

    Apparently I had an old version of the datasheet where the insulation performance was not very well described. I'll check out the ISO7731 you suggested.

    BR,
