WS1A/WS1V Free Range Type Potentiometer Converter
Brand: Yokogawa Electric Corporation
The WS1A/WS1V 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)
- Dual output and 2,000 Vac withstand voltage specifications are available
