About this
manual
This manual describes the Balluff IO-Link I/O module, also called a sensor/actuator hub.
The IO-Link protocol is used to link to the higher-level master module.
Functionally this compact, cost-effective module is similar to a passive splitter box; it records
digital sensor signals and transmits them over the IO-Link interface. It passes control signals
coming over IO-Link to the connected actuators.
