is that any limit on the input current for the digital IO?

Hi all,

  I wonder if there is any limit on input current for the digital IO port. I have a device outputing the voltage about 0.2volt and the manual said the maximum sink current is 25mA. I am going to connect that signal to a DI input in my 6711 card. I wonder if the current is too much for the DI input or PFI?
