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