8WD4 signaling columns

Why stack lights and signaling columns?

The Siemens portfolio of stack lights and signaling columns are industrial tower lights and acoustic warning devices. Use them to supervise complex workflows on machines or in automated processes, and as visual or acoustic warning systems in emergencies.

Complex industrial environments need clear, adaptable signaling for process control and safety. Our signaling columns offer modularity and flexible design. Customize visual and acoustic elements for your needs to provide clear communication and rapid response to operational changes or emergencies.

Enjoy easy installation and high resistance to shock and vibrations for reliable operation in industrial settings. Integrate with AS-Interface or IO-Link for digital connection and diagnostics to enhance process control.
