1. Before Startup
The isolator should only be installed and put into
operation by qualified staff. The staff must have
studied the warnings in these operating instructions
thoroughly. The isolator should only be installed and put into

The loop powered isolator is used for electrical isolation and
processing of 0(4) - 20 mA standard signals.
The loop powered isolator is used for electrical isolation and
processing of 0(4) - 20 mA standard signals.
The galvanic isolation guarantees reliable decoupling of the sensor
circuit from the processing circuit and prevents linked measurement
circuits from influencing each other.

3. Functioning
3. Functioning
The input signal is modulated and then electrically decoupled using
a transformer. The isolated signal is then made available at the
output, demodulated and filtered.

When using loop-powered Isolators, ensure that the current-driving
voltage of the power source U
S is sufficient for driving the maximum
current of 20 mA over the isolator with voltage drop of U drop = 2 V
and the load Rl oad .
