ok so I have a rexroth hydraulic valve that is controlled by 0-10v+ and 0-10v- for the movements in either direction and speed.
the machine controller puts out 0-10v+ for speed but no negative
so what i am looking for is if anyone has done this before and if so would you use an op amp like lm358n? or what?
i have the +-10v power supply (alternating direct current)
and have ordered 2X unos 5X lm358n 2X uno proto sheilds and i have any caps or resistors anyone could possibly need
so whats everyones thoughts? once solved will post entire write up on how its done so if anyone needs it will be available
