3 PRODUCT SCOPE
The processing unit RPV311 and the acquisition modules RA331, RA332, and RA333 offer a distributed
solution for Multifunction Digital Recording. The solution is designed for the acquisition, monitoring and
recording of electrical quantities normally associated with electrical power generation, transmission or
distribution equipment. It is the solution for applications which require flexibility, allowing installation of
RPV311 Processing Unit in existing panels and the Acquisition Modules RA331, RA332, and RA333 near to
the plant seeing monitored the applications installation.
The RPV311Solution is a multifunction equipment with fan-less and no rotating part design. It has an
acquisition system with 16-bit A/D D converters that provide an acquisition rate of 256 points-per-cycle
synchronized by the IRIG-B signal.
It has a high processing capability, which allows the acquisition of up to 64 analog channels and 256 digital
channels divided in up to 8 acquisition modules connected by fiber-optic links. Additionally, it is able to detect
IEC 61850 GOOSE messages.
It allows communication through the electrical Ethernet ports and optionally has a double internal converter
for optical Ethernet interfaces.
Monitoring and configuration are performed through a web interface; also, it has a human-machine interface
on the front panel for displaying information. It has a MODBUS and DNP3 interface for SCADA integration.
The RA331 module allows data acquisition of up to 8 analogue channels (voltage, current, or DC
transducers) and up to 32 digital channels. The RA332 module allows data acquisition of up to 16 analogue
channels (voltage, current, or DC transducers) and up to 32 digital channels. Both modules use 16-bit A/D
converters providing an acquisition rate of 256 points-per-cycle.
The RA333 module allows data acquisition of high-speed analog channels (voltage) for one transmission
line. This module allows the scheme to obtain traveling wave records for fault locating. Additionally, the
RA333 module allows data acquisition of up to 8 analog channels (voltage, current, or DC transducers) and
up to 16 digital channels, using 16-bit A/D converters providing an acquisition rate of 256 points-per-cycle.
