M503 Analog I/O

  • The documentation in the downloads section does not provide information about all the labeled I/O located on the device. Specifically the difference between AI and AIS as well as AO and AOV. Is there more up to date documentation available? Or could you provide us with these specs?


    On a side note, we recieved 2 M503s. On each, RO2.2 and 2.3 are labeled twice, should they actually be 2.4 and 2.5 instead?

    @stephamd The manufacturer made a mistake in one batch of the M503s so that the relays 2.2 and 2.3 are numbered twice. Of course, it should be 2.2, 2.3 and 2.4, 2.5. It will be fixed in the next batch. Is it a big issue for you?

    Regarding the documentation, it is almost ready but there needs to be done some final correction. I will try to take a look at it asap. Sorry for that.

  • We assumed the relays were mislabeled and it is no problem. If you could reply here when the documentation is updated that would be helpful.
    Thanks Tomas
