Voltage and Current Converter/Rescaler
will convert voltage signals in the range of 1-19V or current
signals in the range of 1.33-76 mA into a 4-20 mA non-isolated
signal. This current source signal can be direct or reverse acting
and can be used to drive grounded 4-20 mA loads utilizing a single
power supply. Also accepts an input from a resistive
potentiometer. The unit is a single-input, single-output device,
