SmartLight offers up to 3 modes of operations – stack light, level indicator, and run light – that can be switched on-demand based on programmed conditions to provide process feedback. Multi-purpose models are available with 1, 3, and 5 segments, each of which consist of multiple LEDs and can be programmed for user-selectable colors and brightness levels. IO-Link technology makes products adaptable to network or field-bus, and all configuration/programming is done in controller or PLC.
