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.
