Getting Started
3.2. Mechanical
connection
The modules BNI IOL-25x-xxx-Z013 are attached by using 2 M6 screws and 2 spacers.
3.3. Electrical
connection
The BNI IOL-25x modules have a separate supply voltage connection. Power is provided
through the 7/8” male plug. The module is divided into two segments. 4 or 8 outputs
respectively can be switched for each segment. The segments are galvanic isolated from
each other.
The connection of communication takes place through the IO-Link interface. Power for the
IO-Link interface is provided by the host IO-Link Master directly and it is galvanic isolated
from the supply voltage of both output segments.

Note
The FE connection from the housing to the machine must be low-impedance and
kept as short as possible.
