Network interface – Digital hub
5.1 Installation
For dimensions, see Fig. 4-1 on page 8.
You can find mounting accessories under
www.balluff.com on the product page.
►
Fasten the module with 2 × M4 screws and a
tightening torque of 3 Nm using the mounting holes
(see Fig. 4-1 on page 8).
Requirements for complying with the protection
classes:
For IP67, all plugs and caps must be properly connected
and the tightening torque of 0.6 Nm must be observed
(see data sheets of connectors and caps).
5.2 Electrical connection
1.1.1 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 an intelligent power supply (current
monitoring designed for a maximum of 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.

Installation and connection
NOTICE
Loss of function and damage to the device
Improper setup, e.g., due to incorrect connection or
polarity of the connections, can cause a loss of function
or damage to the product.
►
Take measures to prevent incorrect connection or
reverse polarity.
►
Prevent tampering at the connections.
►
Never exceed a voltage of 36 V at the connections.
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.
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 of the digital outputs.
