I need a digital 4-20mA controller

I need a digital 4-20mA controller

I need a digital 4-20mA controller

(OP)
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

RE: I need a digital 4-20mA controller

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.

RE: I need a digital 4-20mA controller

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

Suggestion: Visit

and type Controls: Digital under Product and Service, which will return 190 companies to inquire about digital controllers
