Project Description
Non-Isolated Audible Frequency (AF) Track Circuit Device
It is a non-insulated track circuit device designed for AC or DC train section where there is electromagnetic interference (mainly generated from the harmonic wave of the electric line power supply). It detects the presence/absence of the train, does not carry a speed code.
Receiving module
Receiving module
Product Information
Receiving module used in stations and for relay and block receives the track circuit signal output from the transmitting module, and generates a voltage of the orbital relay when a normal signal is input to operate the track relay. The operation indicator on the front side of the receiving module can be used to check the abnormality of the module. In addition, it has a built-in monitoring device for collecting monitoring of operation status inside the receiving module.
Features
- Detecting the presence of trains to prevent accidents
- Achieve safe operation of trains by communicating the train speed and vehicle operation information to the locomotive
