Operating logic
The module measures the following electrical quantities: Vrms, Irms, Watt, Var, Va,
Frequenza, Cos and Active Energy, and provides the values in the corresponding
MODBUS registers.
In three-phase environments, measurements given above corresponding to any phase
are available, other than the three-phase value (except the frequency of course).
These measurements are rendered in both floating point and normalised format (except
Frequency and Active energy) between 0 - +10000 (-10000 - +10000 for VAR e Cos ).
Active energy value is stored in memory and when the instrument is switched off, the last
value before switching is kept in memory.
The module output can transmit, via DIP-switch setting, one of the following quantities:
Vrms, Irms, Watt, cos as either a current or voltage value. If the instrument is set for three-
phase measurements, it transmits automatically the three-phase value of the selected
measurement. However, via MODBUS register, the user can choose to transmit the
measurement corresponding to any phase: A, B, C.
The user can set through MODBUS the values
and
of the measurement to

transmit corresponding to 0% and 100% of the analog output. For example, if the signal is
transmitted as current 4..20 mA and the quantity to transmit is voltage Vrms in the 10..300
