std inputs - 4-20mA, voltage supported?

Hi I'm reading through the manual and I'm wondering what the basic information is for the ADC What size ADC (10 or 12 or ? bits)and what level of stability - absolute and temperature drift. Also, are there std interface boards analog interface 4-20mA supported with an excitation voltage 12+V? any ra...
