Hi all.

How to wire potentiometer to Turck IMX12-TI1-2RTDR module?

I think middle wire from pot. to terminal 4.

Other wires from pot. One to terminal 3, and another one to terminal 2 of Turck.

Hello,

I don't have tested on that module connection but I think must be like this in attached picture,

Or if this not help try connect:

3&4 pins and them to Rsstr+ 

2 pin to Rsstr -

1 pin to sense
