■ Precautions for Correct Use
Operation
Passive Loop-powered Isolators draw the power required for isolation
from the input signal.
Here, you must confirm that the current sourcing voltage of the
measuring transducer U
is sufficient to drive the maximum current
B
of 20 mA via the Loop-powered Isolator with a voltage drop U
1.7 V and a load R
.

Thus:
≥ U
= 1.7 V + 20 mA × R
