In all cases, the equipment will compute the line current and the neutral current.
14 Analog DC Transducer Inputs ± 10 V
The RA331, RA332 and RA333 modules have up to 8, 16 or 8 analog inputs,
respectively, which can be configured for measurement of voltages of DC
transducers of -10 V to +10 V. All channels are identified of 101 to 108 for the RA331
and RA333, and 101 to 116 for the RA332.
Each analog input has three terminals: positive voltage, positive current and negative
terminal which are used for the current and for the voltage, as shown in
Figure 121 .
To define if the driver will measure voltage of a DC transducer it is necessary to select
an internal jumper in the module. The binary and analog inputs are galvanically
isolated.
