E.3 The ROR Module
ROR - The protection interface module, Russian version.
Basic functionality of the ROR module is the same as that of RO3. The 4 wire interface of the A/D and
D/A translators without output amplifiers and output/input transformers is connected to "ustrojstvo
sopraženija", which compares local and opposite signals and alters the unit's operation to the two-wire
interface of the comparative protection of DZL.
