The SmartLight all-LED tower light is a fully programmable multipurpose light that offers three modes of operations: stack light, level indicator and run light. The modes can be switched on demand based on programmed conditions to provide process feedback such as cell operation status, tank fill levels and operator progress along an assembly line or to alarm unsafe conditions. The light also has an option for a 95-dB buzzer. Each segment consists of multiple LEDs and can be programmed for user-selectable colors and brightness levels. The product uses IO-Link technology, making it adaptable to any major network or fieldbus.
