  • Convertitore da RS232 a RS485 passivo passivo di livello industriale per comunicazioni a lunga distanza tra dispositivi industriali (commerciali).
  • Il circuito I/O controlla automaticamente il flusso di dati, eliminando la necessità di un segnale di handshake, assicurando che il programma scritto in modalità half-duplex RS232 possa essere eseguito in modalità RS485 senza modifiche.
  • Il soppressore di tensione transitoria (TVS) integrato supporta una protezione da sovratensione da 600 W e una protezione statica da 15 KV, proteggendo efficacemente i dispositivi dai danni.
  • Non è richiesta alimentazione esterna, utilizza una "pompa di carica RS232" per far funzionare il convertitore e può ricevere alimentazione senza inizializzare la porta seriale 232.
  • Adatto per sistemi di controllo accessi, apparecchiature di sorveglianza, apparecchiature terminali, controllo industriale, acquisizione strumenti digitali, microcontrollori, ecc.
