Note:
With power supply units with integrated HART resistance (internal
resistanceapprox.250Ω),anadditionalexternalresistanceisnot
necessary. This applies, e.g. to the VEGA instruments VEGATRENN
149A, VEGAMET 381, VEGAMET 391. Common Ex separators are
alsousuallyequippedwithasucientcurrentlimitingresistance.In
such cases, the interface converter can be connected parallel to the
4 … 20 mA cable (dashed line in the previous illustration).
