miface - Universal Interfaces

The universal interfaces "miface" are used for converting serial interfaces to fieldbus interfaces.

Converter Profinet to serial interface, Dimensions approx. 26 x 105 x 70 mm (KXPN1-RSUNIX3Q24-000)
Converter Profibus to serial interface, Dimensions approx. 26 x 105 x 70 mm (KXPB1-RSUNIX3Q24-000)
Converter Ethernet to serial interface, Dimensions approx. 26 x 105 x 70 mm (KXEN1-RSUNIX3Q24-000)


Product features

  • Robust and suitable for industrial applications

    The universal interfaces of the model series "miface" are equipped with a robust aluminum housing for industrial use.

  • Simple installation and status check

    The mechanical design is made for top-hat rail mounting. Additionally, freely accessible DIP switches are also included, e.g. for selecting the serial interface.The current operating status is indicated via status LEDs.

  • Different protocol converters

    Depending on the model, the interfaces have a fieldbus interface which transmits the data to be transferred in the required format.

    Interface models:
    • miface PN with converter from Profinet to RS232, RS485 or RS422
    • miface PB with converter from Profibus to RS232, RS485 or RS422
    • miface EN with converters from Ethernet to RS232, RS485 or RS422
  • Effective data communication

    The interfaces operate on the communicator principle: Profinet IO RT, Profibus-DP and Ethernet TCP/IP fieldbus data are converted into an electrically isolated serial interface (RS232, RS485 or RS422).

Customer benefits

    ✔ Integration of serial devices into industrial networks

    ✔ Communication application for serial devices in fieldbus

    ✔ Uniform bus structure

    ✔ Cost reduction due to the use of similar interfaces

    ✔ Optimisation of the data structure
