Combi-module with selectable
RS232/RS422/RS485 interface


Product properties:

  • Tiny plug-in interfaces
  • Complete selection of interfaces
    • RS232
    • RS485/RS422
    • RS232/RS422/RS485 (selectable interface type)
    • Profibus
    • 20mA


Background information:
Due to their modular design, all W&T Com-Servers and most W&T PC cards can be equipped with various port types. In contrast to standard devices that are equipped only with RS232 ports, the interfaces of W&T equipment can be modified by simply replacing the existing interface modules with the desired ones.
