1-GENERAL INFORMATION___________________________________
The isolation offered by the DRF series of
Isolated Signal Converters is a 3 way
isolation. Thus, all the benefits exposed
above are applicable to any of the three
circuits composing the instrument : input,
output and power.
Recalibration of the instruments is realized
in a fast and easy way. Opening the front
cover grants access to the configuration
jumpers. Additional Span and Offset
potentiometers are directly accessible from
the frontal part. These potentiometers are
highly decoupled, minimizing the iterations
needed to obtain a correct adjustment.
In order to obtain a higher and quickest
benefit of the DRF units, we recommend you
to read carefully the information provided in
this manual before proceeding to the
installation of the instrument. In this manual
you will find all technical data, both electrical
and mechanical, needed for a correct
instalation and utilization.
Note : The DRF Isolated Signal Converter
instruments have a characteristics label
attached on the side of the instrument. Check
that the information indicated on the label
matches with your application requirements,
and specially check that the value and type of
the power supply needed matches the value
and type of the power supply availble on your
installation.
The DRF series of Isolated Signal Converters,
allow to convert process signals,
temperatures, electrical signals, etc, to current
loops or voltage signals for further
retransmision, while introducing into the
system galvanic isolation barriers between
the input, the output and the power supply
circuits.
The DRF series of Isolated Signal Converters,
offer an excellent relation between signal
conversion speed and measurement
accuracy. Offering a 0.2% accuracy and up
to a 70ms response time depending on the
model, these units can process information
coming from probes or transducers, in such
a way that can be quickly retransmitted in a
fast and accurate form to remote data
acquisition systems or PLC’s. The isolated
signal converters of the ISC series are ideal
to integrate into 12 bit data acquisition
systems.
Its powerful galvanic isolation of 3.500 V
introduces high security to the measuring
systems, preventing the propagation of those
phenomenon which usually cause damage
to the remote system, such as transient
peaks or energy shocks in any of the circuits
of the system. The galvanic isolation also
acts as a strong CE barrier. The decoupling
created between the input, output and power
circuits avoids pernicious effects on the
output, such as ground loops or signal leaks,
which distort the acquired data and are
extremely difficult to isolate once introduced
into the signal.
