▶ OVERVIEW

　USB-302 is an isolated converter that can use 2ch RS232C from the USB interface . The two RS232C ports are isolated independently. 

▶ Features

• • Add 2ch RS232C from USB Use
    FTDI's Hi-Speed ​​compatible 2ch USB / SERIAL chip FT2232H
  • 2ch independent insulation For
    FA applications, noise suppression is safe for insulation.
    Moreover, 2ch is independently insulated.
  • Reliable insulation with resin housing
  • Supports custom baud
    rates In addition to standard baud rates, special baud rate communication is possible.
  • No external power supply required
    External power supply is not required as power is supplied from the USB connector.
  • We will provide your original name plate
    from 50 small lot OEM units .
  • RoHS Directive Regulation 10 No substance used
