Getting Started
3.2
Mechanical
connection
The BNI IOL modules are attached using 3 M4 screws (Item 1, Fig. 3-1/3-2).
3.3
Electrical
connection
The Sensor Hub modules require no separate supply voltage connection.
Power is provided through the IO-Link interface by the host IO-Link Master.
3.4
Function ground
The modules are provided with a ground terminal.
Connect Sensor Hub module to the ground terminal.
Note!
The FE connection from the housing to the machine must be low-impedance
and as short as possible.
3.5
IO-Link
connection
The IO-Link connection is made using an M12 connector (A-coded, male).
