8 FUNCTIONAL OVERVIEW
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.
