You can test if the card is working by connecting Pin #1 to pin #6 - you should get the 10V.
If you insert a resistor in the wire, the value should decrease (20 kOhm ~5V; 1 MOhm ~0,2V ....)

Maybe the possible load of your signal is too low for the ADIN card. You can test that by connecting a 20 kOhm resistor between the GND and the 0-10V output of your sensor (aka create a short-circuit with a 20 kOhm resistor). If the voltage between the connections drop down, the signal load is too low for the ADIN card
