Signal Converter with Galvanic Isolation
The Nokeval 641 Signal Isolator and Converter have current inputs 0/4…20 mA that can be converted into voltage outputs, -10…10 V. These can be converted to 0…10 V, low mV inputs can be converted to standard outputs, and so on.
The 641 Signal Converter accepts 2-wire transmitters without a separate power supply. Potentiometer input comes as standard.
Galvanic isolation is made at the same time as the conversion. Galvanic isolation cuts the noise signals that may exist when using low voltage signals, for example, thermocouples.
