About this guide
This guide describes the Balluff IO-Link sensor collector module, also called the Sensor Hub
/ Actor Hub.
Connection to the host interface master is made through the IO-Link protocol.
Functionally this compact, cost-effective module is comparable with a passive splitter box: It
takes digital and analog sensor signals and passes them over the IO-Link interface.
