BNI LH3-303-S12-K091
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 two different supply voltages: U
S
and U
A
:
– U
S
supplies the module and also the connected
sensors.
– U
A
is the supply for the digital outputs.

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. 2 A for U
S
and 2 A for
U
A
).
►
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)!
