Re: industrial control signals
Sorry for asking, but it is really +-10V? Normaly the industrial signals are 4-20mA or 0-10VOriginally Posted by cncmachineguy

Re: industrial control signals
Even so, if it is really -10V to +10V, i made the attached shematic and the simulation and it worked fine. Probably it can be improved, but since it's 1:30am, and it was made in 5min, i think its good.
If you have 100% PWM you will get -10V, if you have 50% you will get 0V, and if you have 0%, you will get +10V
If you want try it, and post the results.

Re: industrial control signals
Wow cool, thanks gadelhas!! That is really simple, I will gather the op-amps and give it a whirl.
