I need a digital 4-20mA controller

[dmassey]

Hi

I have an machine that takes 0-10V, 4-20mA, or 0-20mA as input for speed control. What I need is a panel mountable digital controller that will allow a user to set speed. It would be best if the controller could scale the input. ie 0-300RPM would be 0-20mA. Can someone point me to a manufacturer of something that will work. Basically a process calibrator, but a permanent panel mount one.

Thanks

I have used Eurotherm controls to do this. The 2416 is a popular one. But any of the instrument companies would have a product that would do it.

Red Lion controls would probably also offer something to fit the application.

Here is a link to a psnsl mount contoller that is front panel programmable for single or multiple pulses per revolution, scaling, and alarm set points.
