Power supply unit
Necessary components:
•
VEGAWELL 52
•
PC with PACTware and suitable VEGA DTM
•
VEGACONNECT with HART adapter cable
•
HART resistance approx. 250 Ω
•
Power supply unit
Note:
With power supply units with integrated HART resistance (internal
resistance approx. 250 Ω), an additional external resistance is not
necessary (e. g. VEGATRENN 149A, VEGAMET 381/391/624/625,
VEGASCAN 693). In such cases, VEGACONNECT can be connected
parallel to the 4 ... 20 mA cable.
