Looking for help to build a circuit to convert analog input to potentiometer output. I am sending an analog signal 0-10vdc via a PLC card. i need to send out a 0-6.2vdc signal through a potentiometer. The reason being, the device (Lincoln welder) is currently being tuned with a potentiometer and has a built in safety circuit. So it is monitoring all three connections of the physical potentiometer and if it detects an issue the welder shuts down. What i am trying to do is use the analog signal to remotely tune the welder and use the digital potentiometer to simulate the physical one. I have 10 welders and limited amount of space in the panel so trying to keep it small.
