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.
