Note
A digital signal (VBUS) is additionally modulated to the
0/4 … 20 mA-output. Acc. to the connected output (e.g.
indicator) this signal is damped by the internal resistor of
the output, if it is smaller than 100
Ω
. For analog inputs of
PLC-systems this resistor is generally
≥
100
Ω
, so that no
damping is caused. In case of a low impedance indicator a
load resistor of R = 100
Ω
must be connected in the
0/4 … 20 mA-line and VEGACONNECT must be
connected to this resistor.
