Figure 12: Links between RPV and acquisition modules configuration section
A The Position represents the position where the acquisition module is physically connected to the RPV311.
Positions A to L.
B The Module scroll box allows user to select the acquisition module used in the link and its characteristics
based on the Part Number of the module. The modules can be:
RA331: Acquisition module with up to 8 analog (voltage, current, or DC) and 32 digital channels;
RA332: Acquisition module with up to 16 analog (voltage, current, or DC) and 32 digital channels;
RA333 (TW): High frequency acquisition module with 3 high-speed analog channels for acquisition of the
traveling waves;
RA333 (DFR): Acquisition module with up to 8 analog (voltage, current, or DC) and 16 digital channels.
C The Fiber length text field allows user to enter the fiber length, in meters, to compensate the delay in the
data transmission between the acquisition and processing modules.
All analog channels have two configuration options. Circuits and channels will be configured based on the
option selected.
In the Inputs section, shown in Figure 13 , it is possible to configure the analog inputs of the acquisition
module connected with the RPV311 configured in the previous section. It is important to configure the analog
inputs for voltage or current, according to the physical configuration of the module, shown in Chapter 14. The
RA333's high-speed acquisition channels do not require configuration, since they are dedicated for voltage
measurement.
