DUCA-LCD / DUCA-LCD96 / DUCA47 network analyzers and multimeters
Country: Italy · Model: DUCA-LCD / DUCA-LCD96 / DUCA47
The DUCA-LCD, DUCA-LCD96 and DUCA47 network analyzers and multimeters measure U, I, P, Q, S, cos φ, frequency, energy and harmonics in single-phase and three-phase low-voltage networks with a 24–240 V AC/DC supply. They are installed in LV boards for technical metering and monitoring of electrical parameters, and the data is sent to SCADA or a PLC over RS485 Modbus, Ethernet, Profibus or 4–20 mA.

Description
The versions differ in the case. The DUCA-LCD and DUCA47 are mounted on a DIN rail next to circuit breakers, and the DUCA-LCD96 is built into a board door as a 96×96 device. The universal 24–240 V AC/DC supply makes it possible to connect the device to a DC control supply or to an AC network without a separate power supply unit. Energy metering takes the cogeneration mode into account, that is, also the energy that own generation sends into the network. Harmonic measurement shows how much non-linear loads distort current and voltage and indicates where filters are needed. Over RS485 Modbus several devices are joined on one bus, Ethernet connects them to the plant network, Profibus is needed for industrial controllers, and the 4–20 mA analog output sends a selected parameter to a PLC or recorder.
How to choose
First decide on the mounting location. For a DIN rail in a distribution board take the DUCA-LCD or DUCA47, and for a board door with the display facing outward the 96×96 DUCA-LCD96 is suitable. Then check the required interface against the model, because RS485 Modbus, Ethernet, Profibus and the 4–20 mA output are not present in every version.

FAQ
What supply does the DUCA-LCD analyzer need?
The device is powered from a 24–240 V AC or DC source. This range covers both low-voltage control supply and the AC network of the board.
What network parameters do the DUCA-LCD / DUCA-LCD96 / DUCA47 measure?
Voltage, current, active, reactive and apparent power, cos φ, frequency, energy with cogeneration taken into account, and harmonics in single-phase and three-phase LV networks.
What communication interfaces do the DUCA-LCD and DUCA47 have?
Depending on the model, RS485 Modbus, Ethernet, Profibus and a 4–20 mA analog output are available. The required interface is specified when ordering.
Can a DUCA network analyzer be installed on a DIN rail?
Yes, the DUCA-LCD and DUCA47 have a DIN rail case. The 96×96 DUCA-LCD96 is intended for mounting in a board door.
Does the analyzer account for energy from a cogeneration unit?
Yes, energy metering in this range also takes the cogeneration mode into account. This is needed at sites with their own generation, where energy flows in both directions.
