Multi-role signalling light towers ‘will define the future’
Published:  21 December, 2021

The German signal tower manufacturer Werma has announced a new generation of towers that, it believes, will define the future of such systems. The whole cylindrical surface of the eSign towers is made up of multi-colour LEDs and can be programmed to perform a variety of roles including alarm signalling, access control, fill level displays, faults, stock information and building security alerts. Various signalling modes can be produced using multiple colours, brightness levels and lighting effects. The towers can also optionally produce acoustic warnings using 10 different tones.

The modular towers offer a choice of 9 or 15 segments that encircle the device. Werma says that they are more conspicuous than traditional towers, and will offer users more colours, effects and individuality. They can be serve as classic “traffic light” displays or be programmed to provide customised displays. The towers can be controlled via IO-Link or configured via USB.

IP66/IP69k protection ensures that the towers will cope with most substances found in production facilities, while their UL 4X enclosures resist UV radiation and environmental influences.

Werma’s eSign signal towers use multi-colour LED arrays across their surfaces which can be programmed to perform a variety of functions

The optional variable-volume sirens that can be configured to suit specific applications and can be can be combined with light effects.
