Series CCT
Signal Converters with isolation
for frequency signals
IDEAL SOLUTION to convert a wide range of analogue signals (process,
temperatures, current, frequencies...) to standard 10Vdc or 20mA process
signals, for further retransmission to a remote data acquisition system or PLC’s.
The galvanic isolation offered by the CCT instruments between the signal circuit
and the remote equipment, reduces to a minimum any eventual problem related
to ground loops between different circuits.

1.- Open the housing to access the instrument internal circuits
2.- Select jumpers on boards «ME», «MP» and «MS»
3.- Connect signal generator to signal input terminals
4.- Connect multimeter to signal output terminals
5.- Power up the instrument as indicated on the label
6.- Generate the low signal level and operate potentiometer
P1 on «ME» until the multimeter shows the desired signal
output
7.- Generate the high signal level and operate potentiometer
P2 on «ME» until the multimeter shows the desired signal
output
8.- Repeat steps 6 to 7 in order to correct deviations and
check the adjust
The CCT has available outputs in voltage and current. Only
one of the outputs can be active. Additional to the standard
0/10 Vdc and 4/20mA outputs, it is possible to recongure
the instrument to any of the outputs shown in the table below.

According to directive 2012/19/EU, electronic
equipment must be recycled in a selective and
controlled way at the end of its useful life.
This instrument has been designed and veried conforming to
the 61010-1 CE Security Regulation, for industrial applications.
Installation of this instrument must be performed by qualied
personnel only. This manual contains the appropriate information
for the installation. Using the instrument in ways not specied
by the manufacturer may lead to a reduction of the specied
protection level. Disconnect the instrument from all external
circuits before starting any maintenance and / or installation
action.
The instrument does not have a general switch and will start
operation as soon as power is connected. The instrument
does not have protection fuse, the fuse must be added during
installation.
The instrument is designed to be DIN rail mounted, inside a
cabinet, protected from direct impacts. An appropriate ventilation
of the instrument must be assured. Do not expose the instrument
to excess of humidity. Maintain clean by using a humid rag and
do NOT use abrasive products such as alcohols, solvents, etc.
General recommendations for electrical installations apply, and
for proper functionality we recommend : if possible, install the
instrument far from electrical noise or magnetic eld generators
such as power relays, electrical motors, speed variators, ... If
possible, do not install along the same conduits power cables
(power, motor controllers, electrovalves, ...) together with
signal and/or control cables. Before proceeding to the power
connection, verify that the voltage level available matches the
power levels indicated in the label on the instrument. In case of
re, disconnect the instrument from the power line, re alarm
according to local rules, disconnect the air conditioning, attack
re with carbonic snow, never with water.
