DB 68
1. Before Startup
When operating the isolating amplifier, certain parts of
the module can carry dangerous voltage! Ignoring the
warnings can lead to serious injury and/or cause
damage!
The isolation amplifier should only be installed and
put into operation by qualified staff. The staff must
have studied the warnings in these operating
instructions thoroughly.
In applications with high working voltages sufficient
distance and isolation as well as shock protection
must be ensured.
Safe and trouble-free operation of this device can
only be guaranteed if transport, storage and
installation are carried out correctly and operation
an maintenance are carried out with care.
Appropriate safety measures against electrostatic
discharge (ESD) should be taken during range selection
and assembly on the transmitter.
2. Short Description
The 3-way isolation amplifier is used for electrical isolation and
conversion of bipolar and unipolar process signals. The signal
combination is selected by the Order No.
The 3-way isolation guarantees reliable decoupling of the sensor
circuit from the processing circuit and prevents linked measurement
circuits from influencing each other. The Protective Separation with
high isolation level provides protection for personnel
downstream devices against impermissibly high voltage.
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, filtered and amplified.
5. Mounting, Electrical Connection
The isolation amplifier is mounted on standard 35 mm DIN rail.
