First Steps
Mechanical
Connection
The BNI IOL modules are fastened with using 2 M6 screws and 2 spacers .
Electrical
Connection
The BNI IOL-104-S02-Z012 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 earth
The modules are equipped with a ground (FE) connection.
Figure 3.2: FE connection
Connect the sensor hub module to the ground connection.
Note
The FE 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).
This connector is used for powering the module. In some devices, this connector is also
used for powering sensors and/or actuators which is connected to the module.
IO-Link (M12, A-coded, male)
Pin
Requirement
1
Supply voltage for module (US1), +24 V, max. 4 A
2*
Supply voltage for actuators (UA), +24 V, max. 4 A
3
GND, reference potential
4
C/Q, IO-Link data transmission channel
* Required when Extension Port activated
Attention!
Overcurrent.
Defective or absent fusing of the supply voltage for the sensor and
actuator will result in their damage or destruction.
Use a fuse or an intelligent power supply (current monitoring designed for
maximum 4 A) which turns off power when overcurrent is present.
