The technology used in the design of the OPC-2 analog Power-Line Carrier terminal is completely digital and uses latest generation elements. This technology together with an innovative signal modulation procedure has produced an equipment with fewer modules but at the same time being just as robust and reliable as its predecessor OPC-1.
There are two different models of the OPC-2 terminal, single-channel and twin-channel, with an output power (PEP) of 20, 40 or 80 W. The twin-channel version of the OPC-2 terminal is obtained by simply substituting the corresponding basic module. In this way, the modules that make up the OPC-2 terminal are integrated in a single 6 s.u. shelf. An additional 3 s.u. shelf only being required in the case of 80 W.
One outstanding feature of the OPC-2 terminal is that it can be equipped with a redundant power-supply module. The chronological register of alarms and events in the OPC-2 terminal is carried out based on its internal real-time clock, being possible to synchronize it with the GPS system.
