features and benefits
The I-7550 converter is specially designed for the slave device of PROFIBUS DP protocol.
It offers RS-232, RS-422, and RS-485 three kinds of communication way.
With the Hybrid COM 1 design, users can readily choose one type of com port to use.
By using this module, users can put their RS-232/422/485 devices into PROFIBUS network very easily.
