Figure 2-32
Connection of a 4 to 20 mA 2-wire transmitter to two instruments in series supplied by L+
from one of the instruments
Every input amplifier is supplied by a differential voltage of 0.2 to 1 V. Instrument 1 also has a
0.2 to 1 V common-mode voltage that is suppressed in this case. Several instruments with a
total common-mode voltage of up to 10 V can be connected in series. As the last instrument’s
input is connected to ground, its input impedance is referred to ground.
As there will be an increased impedance (maximum permissible common-mode v10 V),
the permissible impedance voltage of the transmitter or the on-load voltage may not be
exceeded!
