E1-E6

The ABB E1-E6 designates a range of high-performance, compact, and modular industrial signaling devices, commonly known as signal towers or multifunction stack lights. These are visual and audible alert systems designed to provide clear, color-coded, and prioritized status indication for machinery, production lines, and automated processes.
