DS1 Free Range Type Potentiometer Converter
Brand: Yokogawa Electric Corporation
The DS1 is a nest-mounting type DCS-supported potentiometer converter 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- On-site zero/span adjustment and Input/Output monitoring etc. can be performed from the host system or a handy terminal via the communication interface
