1214C DC/DC/DC Max Voltage on analog input

Hi to everyone, can someone tell me what is maximum voltage that analog input of this CPU can handle without destruction? I can't  find it in the manual. I found it only at analog input card SM 1234 where it is 35V - destruction limit.

Can anyone tell me value for voltage analog inputs of 1214C?

I know that I can measure max 10V but in my application I need to know what will happen in case of some malfunction of other devices when there is possibility to connect 24VDC to analog input of this card (in case of failure of some signal "converter").

Thank you for reply
