Intended purpose
The PROFINET communication interface module CI502-PNIO is used as communication inter-
face module in PROFINET networks. The network connection is performed via 2 RJ45 connec-
tors which are integrated in the terminal unit.
For usage in extreme ambient conditions (e.g. wider temperature and humidity range), a special
XC version of the device is available.
