RAIL TRACK 500

Digital Track Circuit Monitoring Module with Automatic Signal Level

The digital track circuit monitoring module with automatic signal level control DM TCC-AR is a functionally complete track circuit monitoring and coding subsystem with the data reception and transmission via a digital and/or relay interface. The DM TCC-AR module is designed for the existing and newly installed computer-based interlocking systems with audio frequency track circuits for centralized equipment layout.

Advantages

High availability of the monitoring and encoding hardware ensured by redundancy of all components and duplication of communication channels.
Increased resistance to lightning and surge overvoltage.
High noise immunity of the audio frequency track circuit equipment ensured by the advanced methods of digital signal processing.
Elimination of possible human errors due to automatic signal control in the audio frequency track circuits.
Ability to select the track circuit encoding frequency (25, 50 or 75 Hz).
Reduced cost and scope of installation work due to application.

MAIN FUNCTIONS

Monitoring the track circuit vacancy and occupancy and the track line integrity with transfer of the corresponding data to the CBI.
Generation and transmission of continuous automatic cab signaling (ATP) and integrated ATP signals to the track circuits.
Comprehensive protection of the track circuit and coding equipment against lightning and surge overvoltage.
Automatic voltage adjustment at the track generator output, when voltage at the track receiver input is close to the permissible minimum and maximum limits.
Automatic diagnostics of the module components with recording failures and the pre-failure condition of the audio frequency track circuit equipment.
