2.7 Technical specifications
2.7.1 General
specifications
The conditioner and digital weight transmitter DLCNET is designed for interfacing to
strain gauge transducers with collecting data or industrial automation systems via
Profibus-DP®or Profinet®interface.
The board is calibrated in factory in the range of 0 ÷ 4 mV/V and does not
require no further adjustment by the customer.
The board is available in aluminum case for DIN rail mounting.
The instrument allows the transmission of data weight and diagnostics via fieldbus.
The maximum number of DLCNET Profibus-DP®is 128. The maximum number of
Profinet®nodes is limited by application.
In addition to these functionality, the board can be interfaced with a remote display
as a weight repeater (to be installed in safe or hazardous area) through a serial
port RS-485 (in addition to the fieldbus connection).
2.7.2 Principle of operation
The DLCNET module is a load cells signal amplifier. The supply voltage of the
transducer is 5 Vdc with the possibility of 4 or 6 wire connection. With six-wire
connection, you make a correct voltage drop compensation on the connecting
cables, for greater accuracy.
The fieldbus and power supply of the load cell are galvanically isolated via DC /
DC converter, among the 24 Vdc power supply. This allows the connection of
several weighing systems to a data collection system (PLC or PC) with the use of
the same power supply (+24 Vdc) common to other devices without any kind of
problem.

instrument are:
↘Operating temperature: 045°C
↘Storage temperature: 050°C
↘Humidity: 85% non-condensing
2.7.5 Electromagnetic
compatibility
The boards of DLCNET series are equipped with appropriate filtration in order to
meet the EMC requirements that the Directive 2014/34/EU requires.
To improve immunity to radiated interference, emitted by a radio transmitter,
it is important to:
↘Use shielded cables with shielding connected to earth at 100% for
connections to the card.
↘In the presence of earth resistance values low, connect to ground
both sides of the screen to improve the effectiveness of the
shielding.

3 Installation
3.1 Preliminary checks
Verify the status of the instrument through a visual inspection, inside and outside
of it. Any deformation indicate shocks experienced during transport, it could
compromise the normal operation.
Check if the instrument received is intact and complete with all accessories
essential for mechanical and electrical installation.
3.2 Mechanical installation
The instrument in question is supplied in nickel-plated aluminum case for DIN rail
mounting.
Figure 3 shows the mechanical drawing of the instrument.
Figure 3. Mechanical drawing of DLCNET
The instrument must be installed in a safe area in accordance with ATEX
Directive.
The instrument includes a case with IP20 protection. It will be the customer
care to adequately protect the instrument in the installation environment.
In Figure 4 DLCNET-WM mounting is depicted. DLCNET-WM can be installed on DIN
rail.

3.3 Board connections
This instrument is an electrical apparatus: it must therefore be installed by
trained personnel. Start-up, maintenance and the following tests must be
carried out by qualified personnel.
3.3.1 Power supply
Use a power supply cable, with suitable protection to the environment in which
they are installed, with a maximum diameter of 1,5 mm2.
3.3.2 Load cell
The load cell provides a low-level signal (a few millivolts); it is therefore essential
for a correct application, use good quality shielded cables. For single-cell
applications with distance equal to or less than 8 meters is enough the 4-wire
connection.
The connection to the load cells must be done with high quality shielded
cable. The cable CAB-TS6 Logic model is recommended for all industrial
applications including areas with risk of explosion.
In applications with more load cells (platforms, tanks, silos, etc.), It is
recommended the use of junction boxes that minimize differences in impedance or
compensation on the signal branches. The junction boxes JBOX series have been
designed for this purpose and properly solve the problem.
The maximum cable length between the junction box and the instrument, depends
on the specific situation of electrical noise in the plant, which potentially can induce
noise on the signal cable. In normal situations cable lengths up to 300 meters can
be used without problems.
The shielded cable must be positioned preferably in metal conduit grounded and in
any case away from any other power supply cable or power cable.
Verify, before and during the installation of the cable cells, which do not occur
entry of moisture in the same cable, causing loss of insulation and consequent
malfunction.
3.3.3 Ground connections
The ground connection is very important for compliance with electromagnetic
compatibility and therefore for the reliability of the apparatus.
Respect and carefully check ground connections indicated on the attached
diagrams in order to prevent possible malfunctions. Connect the shielded cable to
the GND terminal of the terminal blocks; the other end of the screen normally is
isolated.
In presence of strong interferences (inverter etc.), connect to ground both
heads of the screen. In this case it is important to have low values of ground
resistance.

3.3.4 Data connection
The data transmission takes place through the RS485 serial interface, if you use
the Profibus-DP® protocol and ethernet interface if you purchase the version with
Profinet® protocol. Also in this case it is important to use shielded cables
especially if long or coupled with cables that can induce electrical noise (cables
connected to the actuators, motors, etc.).
3.4 Power supply connection
3.4.1 Layout of the terminal
blocks
The instruments of DLCNET series have three terminal blocks connection, with the
Fieldbus connector, which can be a D-SUB 9-pin connector for the Profibus-DP®
protocol or double RJ45 Ethernet port with integrated switch in the case of
connection in Profinet®(Figure 6, Figure 7).

It recommends the use of power supplies with standard current limitation
(eg.: 24V / 1A with Icc 1,2 A). With power supplies provided with intervention
at short circuit type “Fold Back" or similar are possible problems. The
instrument in question, in fact, absorb a strong current at power for a limited
time (about 4 A for 10 ms).
