1.1. 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.
In terms of function, this compact, cost-effective module is similar to a passive splitter box; it
records digital and analog sensor signals and transmits them over the IO-Link interface. It
passes control signals coming over IO-Link to the connected actuators.
