3 Getting started
3.3. Mechanical
connection
The Module BNI IOL … modules are attached by using 2 M4 screws and 2 spacers.
3.4. 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.
3.5. IO-Link Interface
