3 Getting started
connection The BNI IOL-302-xxx-Z026 modules are attached by using 2 M6 screws and 2 spacers.
connection
The BNI IOL-302-xxx-Z026 modules require two separate supply voltage connection. The supply
voltage of the module is provided through the IO-Link interface by the host IO-Link Master. The
power for the sensors and actuators is provided by the 7/8” connector.

IO-Link (M12, A coded, male)
Pin Function
1 Power supply controller, +24V, max 1,1A
2 not connected
3 GND, reference potential
4 C/Q, IO-Link data transmission channel
5 FE, function earth
Connecting the
hub Connection protection ground to FE terminal, if present.
Connect sensor/actuator supply.
Connect the incoming IO-Link line to the hub.
Note:
A standard 3 wire sensor cable is used for connection to the host IO-Link master.

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