Nokeval 641 Signal Isolator and Converter

The Nokeval 641 Signal Converter is designed to convert standard process input and output signals. Current inputs 0/4…20 mA can be converted into voltage outputs, -10…10 V 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 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 which may exist when using low voltage signals, for example thermocouples.
