Is there a PID process controller available that will have a 4-20ma output based on in put voltage or current? What I need to do is, measure the current load with current transformer on a motor (1 to 20 Amp 100Vdc). This signal go to a PID controller of some type, then be able to set the value it needs to hold and it outputs a 4-20ma signal to control a pressure transducer. As load increases the air pressure needs to decrease to maintain the amp value I set and vise versa. Thanks
