Digital Axle Counter
Complete Digital Solutions For Enhanced Safety & Reliability
For decades, Eldyne’s Multi Section Digital Axle Counters, (Model AzLM) have been known for their reliability, availability, and high levels of safety. To meet the ever-increasing usage and applications, its scalability and its ability to control large areas reliably has made our MSDAC system the lifeline of Signalling System in India.
Eldyne, as Key Industrial Partner of Thales, introduced AzLM in Indian Railways way back in 2002. The AzLM system is approved by German Federal Railway Authority (EBA) and cross approved by RDSO.
AzLM system facilitates a wide range of benefits in achieving functionality, connectivity, seamless integration and diagnostics required for Signalling Solutions.
The system guarantees reliable and fail-safe wheel detection with exceptionally high immunity against EMI covering a diverse range of wheel types and profiles. Today the system is present in more than 40 countries covering arctic to subtropical and desert regions too.
In India, we have the highest installation base of MSDAC system, spanning across all the Zonal Railways and Metro Railways.
