RS232 <> RS422/RS485 interface Industry

Connect interfaces with galvanic isolation...

The Interface connects devices equipped with an RS232 interface to RS422 or RS485 components. The built-in galvanic isolation ensures uninterrupted transmission in industrial environments.

Properties

Interfaces:

  • 1x RS232 port
    • 9-pin Sub-D plug with PC pin assignments
  • 1x switchable RS422/RS485 port
    • 9-pin Sub-D plug
  • Galvanic isolation between the ports
    • Isolation voltage 1kV DC

Management and Connectivity:

  • No re-configuration of transmission parameters required

Power supply:

  • External
    • 12V-24V AC/DC via plug-in screw terminal
    • Galvanically isolated power connection
  • Overvoltage protection

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance per EN 61000-6-2
    • Low noise emission per EN 55032:2015 + A1 Cl. B, EN 61000-3-2 & EN 61000-3-3
  • 5 year guarantee

Run modes

RS422 / RS485 interface:

  • RS422 - Operation
  • RS485 2- and 4-wire - Operation with automatic control of the transceivers
  • RS485 2- and 4-wire - Operaton with handshake control of the transceivers
  • Switchable termination network for RS485 operation
  • No setting of the transmission speed or data format necessary
