Siemens 8WD4220-0FA 50mm Signal Column Buzzer Element, 24V DC, 80dB

The Siemens 8WD4220-0FA is a high-quality 50mm buzzer element engineered for integration into modular signal columns. Operating on a 24V DC power supply, this acoustic signaling device delivers a robust 80dB sound output, ensuring clear status indication in industrial environments. It offers versatile functionality by allowing users to select between continuous or pulsating tone modes, making it a reliable choice for monitoring machinery and control systems.

Advantages

This buzzer element stands out due to its modular design, which allows for quick and easy assembly within existing signal column configurations. Its compact 50mm diameter ensures it fits seamlessly into space-constrained control panels or machine housings. The dual-tone capability provides flexibility for different signaling requirements, while the high sound pressure level ensures that alerts are audible even in noisy industrial settings. Built with Siemens' commitment to durability, this component offers long-term operational reliability and consistent performance.

Suitable for

• Industrial automation and process control systems
• Status monitoring for manufacturing machinery
• Warning signals in assembly lines
• Control panels and electrical cabinets

This buzzer element may not be suitable for outdoor environments where it is directly exposed to harsh weather conditions without additional protective housing. It is also not intended for use in high-voltage applications, as it is strictly designed for 24V DC systems.

Key specifications

• Diameter: 50mm
• Operating voltage: 24V DC
• Sound output: 80dB
• Tone types: Continuous or pulsating
• Compatibility: Modular signal column systems

To use the Siemens buzzer element, simply attach it to the desired position within your modular signal column stack. Ensure that the electrical contacts are properly aligned with the base or adjacent modules. Once mechanically secured, connect the 24V DC power supply to the system according to the wiring diagram of your signal column base. You can configure the tone mode through the internal settings of the module to suit your specific signaling needs.

What to consider before purchase

• Verify that your existing signal column system is compatible with 50mm modular components.
• Ensure a stable 24V DC power supply is available for the unit.
• Assess the ambient noise level of your facility to confirm that 80dB is sufficient for your application.

For optimal performance and longevity, ensure the signal column is mounted in a location free from excessive vibration and that all electrical connections are tightened to prevent signal interference.
