I am using 4-20mA 10 bit

Moved to the correct forum.

For a 4-20 mA signal, do you have the jumpers set properly inside the module?

 

If so, remove the input signal and measure the resistance between the input terminal and the COM terminal.  It should be 500 ohms.  I've been known to connect 24VDC directly to a 4/20 analog input and frying the resistor.

If you swap your inputs around what happens?  ie  A0 and A1 swapped.
