Transponder transmits information signals of RS-485 interface and provides galvanic separation of these signals on both sides.

   Extra Equipment    Interface Adapters

PI-1, PI-2 Interface Adapters

PI-1 and PI-2 interface adapters are intended for providing series communication channels in industrial automation systems.
PI-1 converts RS-232 signals into RS-422/RS-485 signals and PI-2 converts USB (2.0) signals into RS-422/RS-485 signals.
