ith 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, VEGADIS 371, VEGAMET 381. C

ommon Ex separators are

also usually equipped with a sufficient current limitation resistance. In
such cases, VEGACONNECT 4 can be connected parallel to the
4 … 20

mA cable.
