WERMA Signaltechnik is once again expanding its successful "eSIGN" LED signal tower series with a new version featuring a PROFINET interface. The eSIGN series is already much more than a classic signal tower – it is a powerful visual communication system for machines, plants, and production environments. Now, the company's technological flagship offers even more flexibility for integration into complex automation environments – and once again demonstrates what signal technology looks like today: intelligent, networked, and uncompromisingly reliable.

Signal technology reimagined – now also with PROFINET

WERMA has redefined the classic signal tower with the eSIGN series: brilliant LED technology, freely programmable colors and light effects, full-surface signaling, and an elegant, modern industrial design that won the "iF design award 2025." With the new PROFINET version, development is now continuing consistently – towards a fully networked, real-time communicating signaling solution for Industry 4.0.

"With PROFINET, we are enabling our customers to integrate eSIGN even more easily and deeply into existing automation networks," explains Daniel Kensy, Head of Development at WERMA Signaltechnik. "This creates the basis for greater flexibility, easier handling, and maximum transparency in production."

Real-time communication and Power over Ethernet

The eSIGN PROFINET enables real-time communication between the signal device and the control system. Machine statuses can thus be displayed and evaluated without delay – a decisive advantage in automated and safety-relevant applications.

Another highlight: The device is powered via Power over Ethernet (PoE), meaning that data and energy are transmitted via a single cable. This significantly reduces installation costs and material costs and ensures a tidy, efficient system layout. The eSIGN PROFINET supports both PoE and PoE+ and is connected via a 4-pin M12 socket – robust, industry-standard, and future-proof.
