Tab. 5-4: Overview of the IO ports
For the digital sensor inputs, see the directive on
inputs EN 61131-2, type 3.
Due to the high power at the 4 A outputs, high
short-circuit currents may occur and must be
taken into account accordingly in the application
and fusing. The total current of the outputs must
not exceed the total current of the module of 16 A.
Unused ports must be covered with caps to
ensure IP68/IP69K protection.
On the BNI PNT-538-055-P067, all outputs of the
Class A ports are supplied via the sensor voltage.

Installation and connection (continued)
5.2.4 Grounding
To counteract EMC interference, the functional earth
connection must be used.
►
Connect the earth terminal to the functional earth (FE)
of the machine.
The FE connection between the housing and
the machine must have a low impedance and
be as short as possible.
►
Use the grounding strap included in the
scope of delivery.

5.3 Cable routing
Cable length
The Ethernet cable may be max. 100 meters long.
The IO-Link single-ended cordset may be max. 20 meters
long.
