RS232 to RS422/RS485 isolated converter, AD400Ei

De AD400Ei is een universele compacte RS232 naar RS422 / RS485 converter met galvanische scheiding tussen beide poorten. Deze galvanische isolatie beschermt de RS232-poort van de pc en vermijdt "aardlussen". De RS232 sub-D9-poort kan rechtstreeks op pc's worden aangesloten. De RS422 / RS485-poort is een schroefklemmenblok. In de half-duplex RS485-modus schakelt de converter automatisch tussen verzenden en ontvangen. De omvormer wordt extern gevoed.
