BNI LH3-303-S12-K091
Network interface – Digital hub
4.2 Function
IO-Link hubs communicate with the higher-level IO-Link
master module via IO-Link. The connection is made via the
IO-Link protocol.
In terms of function, the hub module is comparable to a
junction block: Detection of the digital signals and
forwarding via the IO-Link interface or forwarding of the
digital control signals, which come via IO-Link, to
connected actuators.
The IO-Link hubs have four freely configurable ports and
four input ports, as well as eight standard outputs, each
with a power rating of up to 200 mA.
Port 8 (X08) can be configured as an extension port to
expand the hub with a second
hub(BNI LH1-303-S11-K091 or BNI LH3-303-S12-K091).
This allows the number of available I/O channels to be
almost doubled.
