Werma 657.100.55 is a high-performance multicolour signal tower siren featuring 9 LED light elements and an integrated siren designed for industrial automation applications. This versatile unit provides combined audible and visual signals for machine status and safety alerts, helping to enhance operational safety and efficiency in manufacturing, packaging, food processing, and logistics environments.
The signal tower supports multiple mounting options including tube and base, enabling installation flexibility in limited space control cabinets or on pillars. Its rugged design offers IP69K and IP66 ingress protection, making it ideal for harsh conditions that require regular washdowns with high-pressure water jets and dust exposure.
Running on a 24V DC supply, the device maintains a steady current draw of 405 mA, enabling straightforward integration with PLC outputs and predictable power management. The siren produces a maximum sound level of 105 dB at 1 meter, sufficient for alerting personnel even in extremely noisy areas.
The nine independently visible multicolour LED segments provide layered and clear visual indication of process states, assisting in quick diagnostics and safety signal recognition. Operating from -30°C to 60°C temperature range, it suits indoor environments with challenging climate conditions.
Multifunction signal tower combining visual and audible alerts for industrial control systems. LED-based illumination lowers maintenance intervals due to long life and reduced heat output. M12 plug terminal connections simplify installation and reduce wiring time.
Complies with RoHS standards ensuring environmentally responsible manufacture. Black housing enhances durability and blends with standard industrial equipment.
This Werma eSIGN Series signal tower siren is widely used for machine status indication on production lines, safety signalling in assembly and packaging cells, and audible evacuation alerts in logistics hubs. It is particularly suited for demanding industrial, food processing, and manufacturing environments requiring reliable status communication and durable equipment.
