This is an old post but I had the same issue with the URA-0800O Analog Input module using the URB-TCP adapter. My application involves the temperature monitoring from -100 to 100°C. I also used the two Built-In Analog Inputs of my US7-B10-TR22 Controller without problems.
The linearization block works well with negative to positive values for the Built-In Inputs, but not for the Remote Inputs. I tested the linearization block with X1=0, Y1= 0 and X2=4095 Y2=200 and it reads accurately for the remote, so I ended moving the result to a formula block and substracting 100. In that way when the controller reads 0 it will be -100 and when it reads 200 it will be 100, keeping the same original span (200).
I hope this helps somebody!
