Protecting 0..10 Vdc PLC input from voltage divider failures
A 12-15V Zener across the 1k will be good, Zeners above 10V or so tend to have a fairly sharp knee, but pick one with a leakage current of less than a few microamps at the 10V full scale of the card to avoid it distorting the reading. The one you list is good, though it's overkill on power rating.
