► Before Startup
When operating the signal converter, certain parts
of the module can carry dangerous voltage!
Ignoring the warnings can lead to serious injury
and/or cause damage!
The signal converter should only be installed and
put into operation by qualified staff. The staff must
have studied the warnings in these operating
instructions thoroughly.
The signal converter may not be put into operation if
the housing is open.
In applications with high operating 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.
► Short description
The Shunt/mV Isolation Amplifier is used for separation and
conversion of bipolar and unipolar mV signals such as those
frequently used for current measuring with shunt resistors or other
applications with low sensor voltage.
The input and output range can be set by using DIP switch and due
to the calibrated range selection no further adjustment is necessary.
A switchable compensation of the measuring range can be
performed at the Zero/Span potentiometers on the front panel. Also
the cut-off frequency can be adapted to the measurement task by
using the DIP Switch.
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.
The auxiliary power can either be supplied via the connection
terminals or via the In-Rail-Bus connector (see accessories).
► 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.
► Settings
Set the input and output ranges with DIP switch as indicated in the
following table:
