Communication converter
In most cases substation is unmanned. The substation devices are connected to the star point, and the star point is joined to computer network, which enables continuous monitoring of substation. The connection of a few OPG-1/2/IZ devices serves as communication equipment which allows to configure both telecontrol ans diagnostic purpose communication channels. Such connection enables connecting many different devices of different types and transfer data through one communication channel.
