We have a Nion n6 at a theme park that appears to have some dead GPIO inputs: Voltage or no voltage there is no change of state seen in the software (inputs are seen as permanently ON in NWare).
When measured, the GPIO input voltage was a little over 28v DC (!). What is the maximum allowable sustained voltage on a Nion GPIO input pin? Would a sustained 28v DC input be likely to damage the GPIO?
Thanks,
Martin

The maximum input voltage is 24VDC.
If you were sending it 28VDC for an extended period of time, you may have damaged those input pins.

Thanks, that's what I thought.
