Werma eSIGN Series Multicolour Signal Tower Siren, 9 Lights 24V Tube, Base

Werma eSIGN Series Signal Tower, 24V Supply Voltage, 105dB Maximum Sound Level - 657.100.55

This signal tower provides multi-function visual and audible indication for industrial control and safety systems. Designed for panel, tube or base mounting, it combines multicolour LED signalling with a built-in siren to communicate process states clearly in harsh environments. The unit operates from a 24V DC supply and is suitable for installation where a compact, high-output warning device is required.

Features and Benefits:

• Nine independently visible segments deliver layered status information
  105dB sounder outputs high-volume alerts for noisy areas
  IP69K and IP66 ingress protection enables washdown and dust resistance
  Operating range from -30 to 60°C supports extreme indoor environments
  M12 plug terminals simplify wiring and reduce installation time
  405mA current draw provides predictable power budgeting

Applications

• Suitable for machine status indication on production lines
  Ideal for food processing areas requiring high-pressure washdown
  Used for safety signalling in assembly and packaging cells
  Can be used for logistics hubs needing audible evacuation alerts

What type of illumination technology is used and how does it affect maintenance?

It uses LED elements, which reduce service intervals due to long life and lower heat output compared with discharge lamps.

How is the unit mounted when space is restricted?

It can be installed on a tube or fixed to a base, allowing flexible footprint choices in confined control cabinets or on pillars.

What housing characteristics support harsh industrial cleaning processes?

The enclosure meets high-pressure and high-temperature washdown protection levels, preventing ingress from water jets and contaminants.

Which electrical characteristic is important for integrating with PLC outputs?

The device runs on a 24V DC supply and presents a steady current consumption figure useful for calculating total load on output drivers.
