User’s Manual DRF Series
GENERALINFORMATION
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 up to a
0.2% accuracy and down to 70ms response time, 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 DRF series are ideal to integrate into 12 bit data acquisition
systems.
Its powerful galvanic isolation of 3500 V introduces high security to the measuring
systems, preventing the propagation of those phenomenon which usually cause
damage, 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 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.
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.

in a fast and easy way. Opening the front cover grants access to the configuration
jumpers. Additional Span and Offset potentiometers are directly accessible
fromthefrontalpart.Thesepotentiometers
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 Series Isolated Signal Convertershaveacharacteristicslabel attached on the side of the instrument. Check that this information matches with your requirements for the specific application, and especially check the value and type of the Power Supply.
