2-wire Converter 4-20 mA Isolator
The Nokeval 6580 is a very slim, only 9 mm, 2-wire converter with galvanic isolation. The converter is powered by output 2-wire loop. It is specially suited to isolate analog inputs of programmable logics because those supply the power and wiring is simple.
The idea of connecting power supply to output side eliminates typical problems of conventional isolators like small output load and high input side voltage drop. Three input types are available: 0..20 and 4..20 mA or 0..10V, output is always 4..20 mA. Output load is 700 Ω by 24 VDC power supply.
What is a 4-20ma Isolator?
A 4-20mA isolator is an electronic device used in industrial applications to protect sensitive equipment by electrically isolating and transmitting a 4-20mA current signal.
