Nokeval has designed a very slim, 9 mm only, 2-wire converter with galvanic isolation. 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.
