The IO-Link Smart-Light from Balluff is now available in three versions. In addition to the previous version with a maximum of five segments, there are now two more with three and one segment respectively - with or without acoustic signaling. They can be adapted via hardware without the need for complex configuration. The usual combination of different colored modules to form a luminaire is no longer necessary, as it can also be adapted to its new task "on the fly" via the control system. According to the manufacturer, tendencies, progressions and trends of physical variables can also be displayed. Temperature states, fill levels of systems or even the position of a slide via a position measuring system can be visualized on the column, which is up to 20 LED lights high. An unshielded three-core sensor cable is all that is needed for connection and installation. The LED signal tower offers three operating modes: 'Stacklight', 'Level' and 'Run'.
