Voltage & Current Converter / Rescaler VTI Series

Voltage & Current Converter / Rescaler

 

The VTI Series voltage and current converter/rescaler will convert voltage signals in the range of 1-19 volts into a 4-20 mA non-isolated signal. The voltage to current converter can also convert current signals in the range of 1.33-76 mA into a 4-20 mA non-isolated signal. The resulting current source signal can be direct or reverse acting for a variety of building automation and HVAC applications. These voltage to current converters can be used to drive grounded 4-20 mA loads utilizing a single power supply. The VTI also accepts an input from a resistive potentiometer. The VTI-1 is a single-input, single-output device, and the VTI-2 accepts a single input and provides dual outputs.
