I am trying to scale one range of input voltages to another output voltage range for a small side electrical project I have going on at a textile manufacturing floor. I think this can be done with a differential amplifier and some voltage dividers for input reference points, but am having some issues getting the wheels turning.
We are using an actuator pedal that provides a 0-10V DC output signal. The pedal is bidirectional, with the system set to idle at 5V (center). I would like to take this signal as an input to a circuit that converts the range to 0-10V in either direction. So:
5V to 10V should output as linearly as possible to 0 to 10V. (farthest away from neutral = 10V.)
5V to 0V should output as linearly as possible to 0 to 10V. (farthest away from neutral = 10V.)
Throughout some of the range, it seems like a differential amplifier would work. I keep thinking of a simple Vo=AVi basic op amp transfer function, such as gain in the form of (10V-0V) / (10V-5V) = 2 for the gain, but I don't know if it's that simple, nor understand how the resistor arrangement should work.
On the low end of the voltage range, I feel like the same thing applies, but am inexperienced in inversing/negating voltages in circuits.
Any reference material or solutions one could recommend?
Danke,
H
