Mitsubishi card A1S64AD is it blown?

one of our guys has send 24vdc from the power supply strait into the analoge input. The card now will not recognise any current over 14.5mA I have tryed resetting the offset with a 20mA input but no sucess.. is the card channel blown? do i use a spare chanel (not much programming experence mind) but willing to have a go!
Ideas
thanks

Typically, the 0-10VDC inputs are rated to 15V. 4-20mA to 32mA. So if you shot it with much more than that, it's possible that it damaged the components.

To verify, try another card.

verified! 3 cards with blown chanels..
