More than just a signal tower | Auer Signal News & Blog

The PC7 signal tower is not only a highly effective stack light for up to seven modules, but also functions as a standalone 70mm warning beacon with just a single module, thanks to its modular design.

This flexibility enables a wide range of applications, as the modules can be easily combined, replaced, and expanded according to specific requirements.

Top and Inline Modules: What's the difference?

The PC7 consists of two module types, both of which can also be used as standalone signal lights in a single-module configuration, depending on the application.

 

Top Module

  • Ideal for use as a standalone 70mm warning beacon
  • Warning beacon module with a hemispherical lens design
  • Twice the light output compared to inline modules
  • Sealed surface, optimized for daily cleaning (IP66/IP67)
  • Can be combined with sound module





Inline Module

  • Optimal horizontal light distribution
  • Easy extension with additional modules
  • Can be combined with sound module

 

 
 

 

Single modules as fully functional warning beacons

A PC7 base combined with a top module creates a fully functional 70mm warning beacon with a 180° light distribution. With a height of 80 mm, the top module is comparable to other medium-sized signal beacons but significantly outperforms similar products in terms of brightness.

The top and inline modules are available with various functions:

  • steady light module
  • rotating light module
  • steady/flashing module
  • multi strobe module
  • multi color module
  • multifunctional module

PC7 as a fully functional IO-Link beacon

The product portfolio includes two different IO-Link bases, enabling conventional PC7 light modules to be used as cost-effective and fully functional IO-Link signal beacons.

 
 

Pre-assembled PC7 beacons

For the most commonly used PC7 single light combinations, pre-assembled models with dedicated short part numbers are available.

Conclusion: PC7 – a flexible, modular and versatile signal beacon

Many signal towers are used as 2- or 3-stage traffic light solutions. However, the PC7 offers much more: Thanks to the modularity and functionality of its individual modules, it can serve not only as a conventional signal tower with up to seven positions but also as an optimized 70mm warning beacon when equipped with top modules.
