New signal tower Modul Perfect 70 - PC7

The new signal tower from Auer Signal is a very special one: the Modul Perfect 70, better known as PC7, is one of the most versatile signal towers. In terms of creative design, performance, application possibilities, and future suitability, it just can't get any better, according to Auer. Read more about signal towers and pillars.

The successor of the Modul-Signal 70

The Modul-Perfect 70 is the successor to the Modul-Signal 70. The signal tower is structurally identical. The flat design without edges, grooves or recesses prevents dirt, dust and other residues from accumulation on the lenses and suffered in industrial settings. The signal tower is therefore not only more attractive but also easy to clean and does not leave any form of dirt on the signal tower. The flat design prevents dirt from entering the signal tower and prevents malfunctions. The PC7 has a degree of protection of IP66 and can withstand temperatures from -30°C to +70°C. The cylindrical form is also continued in all possible modules. Read more about signal towers and stack lights.

Hemispheric effect

The top module of the Modul Perfect 70 is even brighter than the standard modules. Unlike the standard modules, the upper module has a hemispherical effect. This means that the light intensity of the upper module is the same at all angles of incidence. This ensures that the PC7 can be used in a larger number of applications. The top module can be combined with an inline tone module and with a basic module to form a standalone optical-acoustic signaling device.

The technology of the Modul Perfect 70 - PC7

  • Unique, patented contacting via the circuit board
  • Semi-automated manufacturing in Vienna, Austria
  • Highly future proof and flexible for making customer-specific adjustments
  • The mid-power LEDs used have a similar output to competitor products with high-power LEDs
  • All modules are only available in 24 V AC/DC. Corresponding mains adapters are available for connecting to 230 V AC (PC7BHV3 for max. 3 modules and PC7BHV7 for max. 7 modules)
  • This has enabled a significant reduction in the number of individual components
  • With the nano-coated diffuser films, it is easy to change the appearance of each individual light module yourself
  • The easy-to-program voice output module can play up to 7 different voice messages or melodies
  • The new cost-effective M12 connector combines the mounting of the connector with the electrical contacting
  • Certification: CE / cULus
  • Degree of protection: IP 66

Perfect clarity

Comparison clarity PC7

The signal tower PC7 is up to 13 times brighter than the previous model Modul-Signal 70. The PC7 is six times brighter than signal towers from competitors. The PC7 is perfectly visible even in conditions with a lot of light!

The highest signal tower - up to 7 positions

With 7 positions, the PC7 is one of the most versatile signal towers out there. The unique, patented contact allows up to 7 positions thanks to 8 internal contacts. As a result, the PC7 is not only the highest signal tower but also the one with the most combination options. This makes the tower future-proof and equipped for every application.


Multi-color module

7 colors can be switched externally in the LED multi-color module: red, yellow, green, blue, transparent, magenta and turquoise. Thanks to binary switching, 4 additional modules can be used in addition to a multi-color module.

Rotating light module

The PC7 is the first signal tower with a LED module with rotating light. This rotating light module can be operated with 2 rotational speeds - 90 and 180 rpm - via a DIP switch.

Multifunctional module

Continuous light module | Auer Signal

The PC7 multifunction module offers continuous light, flashing light, strobe light, and dual strobe light functions. The different functions can be defined by the user via a DIP switch in each module.

Continuous light module

The PC7 LED light module is the ideal choice when it comes to standard applications. But when we say 'standard', we mean functions that other suppliers only offer on expensive, high-performance modules.


The top of the towerBright top module | Auer Signal

The top module is even brighter than the standard light modules and has an extensive, hemispherical signal effect. The top module ensures that the PC7 can be used in a larger number of applications. Combine the new top module with an inline tone module and a basic module. You create a 'high performance' visual and audio signaling that can be used in a large number of applications.

Diffuse modulesDiffuse films | PC 7

One module, two appearances

The diffuse films can be placed effortlessly in each individual module, even at a later time. Without changing the signal effect too much, you can choose between a clear or a diffuse signal with the help of the new diffusion foils. This allows the PC7 to deliver a single tower with two different forms.

The appearance of the signal tower can be changed quickly and easily:

  • Light modules without diffuser film emit a bright radiation pattern and meet the highest performance requirements in terms of luminous intensity. 
  • Light modules with diffuser film emit a stronger colour contrast and a more homogeneous radiation pattern. 


Tone modules

Inline tone module | PC 7 | Auer Signal

Multi-tone module

The new inline tone module of the PC7 can be placed at any position in the tower. DIP switches can be used to select one of eight tones with an adjustable volume of up to 105 dB.

Multi-tone alarm sounder module

With the sound capsule, the multi-tone alarm module offers significantly better tone quality than the multi-tone module. 7 different signal tones can be externally activated from a total of 80 via 3 inputs.

MP3 / voice output module

With the MP3 / voice output module you can select and play up to 7 different voice messages or melodies. The MP3 / voice output module can easily be programmed and adapted by the customer in advance via a USB interface. View MP3 module in the webshop.
