Convertitore di interfaccia seriale PSM-ME-RS232/RS485-P
Convertitore da RS232 a RS485 con isolamento elettrico
- Conversione da RS232 a RS422 o RS485
- Velocità di trasmissione fino a 115,2 kbps
- Supporto di full duplex e half duplex
- Isolamento elettrico a 3 vie
PSM-ME-RS232/RS485-P esegue una conversione bidirezionale dei segnali dell'interfaccia RS-232 verso lo standard RS-485 a 2/4 poli e RS-422.
Grazie al supporto di una comunicazione full duplex bilanciata a 4 poli o half duplex a 2 poli, PSM-ME-RS232/RS485-P è adatto alla maggioranza delle applicazioni, come ad esempio quelle industriali, commerciali e qualsiasi altra applicazione che utilizza dispositivi informatici da ufficio di tipo generico. È possibile applicare velocità di trasmissione fra 1,2 kbps e 115,2 kbps alle reti point-to-point e point-to-multipoint.
È possibile utilizzare PSM-ME-RS232/RS485-P in tutti i sistemi con bus comune con formato dati UART/NRZ e lunghezza dei caratteri di 10/11 bit. Si tratta della migliore soluzione “plug and play” per la conversione di RS-232 (V.24) in RS-422 (V.11) e RS-485 con isolamento elettrico.
Caratteristiche dei Convertitori RS232 a RS485
- RS-422 a 4 poli per il funzionamento point-to-point
- RS-485 2 poli, half duplex
- RS-485 4 poli, full duplex
- Alternanza automatica di trasmissione e ricezione
- Velocità di trasmissione comprese fra 1,2 kbps e 115,2 kbps
- Indicatore dati integrato per l'indicazione dinamica dei dati di trasmissione e ricezione
- Isolamento a 3 poli ad alta qualità fra alimentatore, V.24 (RS-232) e RS-422/485 per uno scollegamento affidabile dei potenziali con 1,5 kV
- Protezione dalle sovracorrenti integrata con scarico transitorio nella guida DIN
- Approvazione cantieristica per DNV
