Axle Counters

Get to know more about Frauscher's latest axle counters FAdC and FAdCi and our solutions for future signaling

With its functional modularity, flexible scalability and an Ethernet-based software interface, the FAdC permits a wide range of configurations. The savings on space, energy and investment costs increase with project scale thanks to state-of-the-art communications technologies. For example, the operation of small, centralized systems is just as possible as the implementation of complex systems.

Connection to a high-performance electronic interlocking is possible both via a customer-specific interface and the Frauscher Safe Ethernet (FSE) protocol. In this way, higher-level applications can be provided with all the functional and diagnostic information required. In addition, clusters that are spread along the track can also be connected via the Ethernet to form a decentralized architecture.

The FAdCi has been specially developed for less stringent safety requirements. This means a cost-effective type of the latest generation of axle counters is available for simplified operational conditions. This axle counter fulfils all requirements in accordance with the CENELEC standards up to SIL3 and has been designed for use at speeds up to 50 mph.

The FAdCi also provides all the benefits offered by the basic model: Functional modularity, easy scalability in conjunction with the optional software or hardware interface, as well as the greatest flexibility in terms of configuration for a variety of requirements. In addition to train detection, a large variety of further diagnostic information and data is generated in a wide range of applications.

System Structure

Frauscher wheel detection systems are predominantly applied as an integral component of axle counters in train detection systems. These combine high-availability and highly-resistant wheel sensors with innovative evaluation boards.

On this basis, Frauscher axle counting systems function at the highest levels of safety, offering absolute precision and reliability.

Frauscher wheel detection systems consist of outdoor equipment — namely a sensor with a claw and cables — and indoor equipment, in which the evaluation boards are housed. These therefore form the basis of Frauscher axle counters.

The data that are collected are made available to higher-level systems via flexible interfaces.

Outdoor equipment

The outdoor equipment is composed of the sensor, mounted on one of the running rails, the trackside connection box and the cables that connect them. Frauscher wheel sensors are mounted on one of the running rails easily, quickly and without the need for drilling, using rail claws. This reduces the time spent by personnel in a hazardous area to a minimum.


  • High-availability wheel sensors
  • Simplified mounting
  • In-house accessories
  • Maintenance-free operation

Indoor equipment

The data from the sensor are transmitted to the indoor equipment. At this point, the AEB and AEBi evaluation boards of the FAdC and FAdCi take over the evaluation of the information supplied by the sensor as well as the counting of axles. Data generated in this way are transmitted to the communication board, which provides the acquired data to higher-level systems via various interfaces.


  • Perfectly coordinated components
  • Flexible configuration options
  • Option for decentralized architecture
  • Minimal space requirements


Efficient software interfaces are what make the FAdC and the FAdCi stand out in particular. System integrators have the opportunity to implement the Frauscher Safe Ethernet (FSE) without using their own software protocol. Alternatively, customer-specific protocols can also be integrated. It is also possible to connect existing systems via hardware interfaces such as optocouplers or relays.


  • Flexible interfaces
  • Vital data transmission
  • Wireless communication is possible
  • Simple integration


Frauscher Diagnostic System FDS

Frauscher offers comprehensive diagnostic options for the reliable operation and easy, cost-effective maintenance. The FDS is adapted according to the size of the system in question and can be quickly expanded as required. Faults can already be identified in advance by means of warning messages and so potential faults are avoided by means of preventative measures. An XML interface also enables the acquired data to be forwarded to customer-specific diagnostic systems.

Frauscher Configuration Tool FCT

The FAdC supports all processes from the scheduling, project design, configuration, diagnostic and simulation stages through to adaptation and maintenance using innovative software tools. The potential for considerable savings is the primary benefit of the Frauscher Configuration Tool FCT. It enables customers to carry out configurations, diagnostics and simulations themselves. Track layouts can be reproduced quickly and easily using the drag-and-drop function. All other information, such as configuration data and the design documents, are created automatically.
