First Steps
3.2.
Mechanical
Connection
The BNI IOL modules are attached using 2 M6 screws and 2 washers.
3.3.
Electrical
Connection
The 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.
Function ground
Fig. 3-3: Ground connection using mounting screw
Note
The function ground connection from the housing to the machine must have
low-impedance and is made using the mounting screw.
IO-Link
connection
The IO-Link connection is established via an M12 connector (A-coded, male).
