Communication converters and repeaters
(1. generation)

Communication converters and repeaters are intended for converting the RS-232, RS-422 and RS-485 signal levels. They can be used in any application requiring asychronous serial communication.

All types are suitable for industrial control systems, building in the switch boards, etc. The coverters need an external power supply (24V or 12V), both communication lines are isolated to the power supply and to each other (three-way isolation).

The converters provide the circuits for RS-485 Automatic Data Flow Control (ADFC) or the RTS and DTR signals can be used. They also provide overvoltage protection components and the line termination impedances.
