FS1A/FS1V Free Range Type Potentiometer Converter
Brand: Yokogawa Electric Corporation
The FS1A/FS1V is a compact, front terminal connection type potentiometer converter that is used in combination with an instrument such as a control valve which outputs the change in resistance of potentiometer.
It converts the change in resistance into isolated DC current or DC voltage signals.
Features- Input Range Setting, Burnout Setting, I/O Monitoring, and Zero/Span Adjustment can be Made using the Optional Parameter Setting Tool (VJ77) or Handy Terminal (JHT200)
