BNI IOL-314-S52-P012 / BNI IOL-314-S52-P071
Network interface – Digital hub
The supply voltage for the module is provided via the
IO-Link interface from the higher-level IO-Link master.
There are three different supply voltages: U
S1
, U
S2
and
U
A
:
– U
S1
supplies the module and also the connected
sensors. (Variant ...P012).
– U
S1
supplies the module only (Variant ...P071).
– U
S2
supplies the connected sensors. (Variant ...P071).
– U
A
is the supply for the digital outputs.

Auxiliary voltage connection (XD1)
The BNI IOL-314-S52-P071 variant has an L-coded M12
auxiliary voltage connection. This connection allows more
power to be supplied for the sensor and actuator systems.

Current limitation when using the extension port
– Variant BNI IOL-314-S52-P012
Observe the current limitation: The output is split 1:1
between the first and second device.
– Variant BNI IOL-314-S52-P071
There is no current limitation to consider because the
current for the second device is supplied independently
via the auxiliary voltage connection.
Power supply
NOTICE
Unwanted voltage dips
Non-separated electric circuits of the power supplies for
sensor and actuator can lead to unwanted voltage dips
of the sensor supply when switching actuators.
►
Fuse the power supplies for sensors and actuators
separately.
►
Make sure that the power supply of the device is
sufficiently dimensioned to cover start-up and peak
currents and design the fuse protection concept
accordingly.
NOTICE
Overcurrent
Defective or missing fuses in the power supply for sensor
and actuator will damage them.
►
Use a fuse or intelligent power supply (current
monitoring designed for max. 4 A for BNI IOL-…-
-P012 or 16 A for BNI IOL-…-P071).
►
Connect the protective earth conductor to the FE
terminal.
►
Connect the incoming IO-Link line to the sensor hub.
NOTICE
Loss of function and property damage
Improper installation, e.g. due to misconnection or
incorrect polarity of the connections, can result in a loss
of the function and property damage.
►
Take measures to prevent misconnection or polarity
reversal.
►
Prevent tampering at the connections.
►
Never exceed the value of 36 V between any of the
pins.
If possible, supply power to the sensor/module
and actuator using an independent power source
to ensure independent operation in the event of a
power failure.
For UL: observe cable requirements and power
supply requirements (siehe section
UL requirements)!
