The signal tower 8WD4420-0FA is a summation element that can emit a continuous tone or pulsing sound, reaching a volume of 85 dB. It is available in black and is suitable for AC/DC 24 V. With a diameter of 70 mm, it is ideal for the modular construction of signal towers, for example, for visual and/or acoustic warning devices or for monitoring complex processes.

Thanks to its high protection class, these robust devices are industrial-grade and extremely resistant to shock and vibrations. The secure bayonet lock allows for easy installation and quick replacement of the acoustic elements, which are adjustable in tone and volume.

In addition to continuous light, flashing, blinking, and rotating lights in various colors and voltages, as well as buzzers and sirens, are available. These come in different diameters and can optionally be communication-capable via connection to AS-Interface. The use of multiple LEDs in a light module ensures optimal light distribution.

Accessories such as bases, tubes, adapters, light bulbs, LEDs, and tube adapters are available. The SIRIUS 8WD signal towers are modular and communication-capable.
