Hello,
All dosage pumps I have ever used has a 4-20mA command signal and seperate supply.
Now, the customer has a pump with a 24 Volt DC motor. Speed is to be controlled by varying supply voltage 0-24 V. It's a small motor and I have not yet found out the current but it is low.
So, I need some way so that a 4-20mA or 0-10V signal from my PLC can control 0-24V to the motor. Ideas???
