Signal columns - modular, compact and capable of communication

On machines or in automated processes, signal towers are important visual aids for controlling complex processes. In emergency situations, they serve as visual or acoustic warning devices. They can be flexibly designed with continuous, flashing, strobe and all-round light as well as acoustic elements. Whether in modular or compact design - they are easy to install and extremely resistant to shock and vibration. Optional communication options with AS-Interface or IO-Link enable digital connection and diagnostics.
