First Steps
3.2. Mechanical
Connection
The BNI IOL modules are attached using 2 max. M4 screws and 2 washers.
3.3. Electrical
Connection
The BNI IOL-309-002-Z019 modules do not require a separate supply voltage connection.
Supply voltage is provided via the IO-Link interface and the higher-level IO-Link master
module.
Functional
ground
The modules are equipped with a ground connection.
Figure 3-3: BNI ground connection IOL-309...
Connect the sensor hub module to the ground connection.
Note
The functional ground connection from the housing to the machine must have
low-impedance and be kept as short as possible.
IO-Link
connection
The IO-Link connection is established via an M12 connector (A-coded, male).
