The Single Section Digital Axle Counter SSDAC Singal section axle counter is generally used to monitor a single track section i.e. there is only one entry point and one exit point for a particular track section.
Examples of applications of axle counters are:
- Train detection in station section
- Train detection in automatic signaling section for signal control
- Train detection in the block section for block proving
- Train detection in Railway yards
The SSDAC-710P uses its track sensors on each end of a track section to continuously monitor and count the train axles passing in and out of that section. If the number of axles in the section is zero and there are no defects or disturbances, the system declares the section to be unoccupied. This is typically signaled by picking up a relay. In all other cases, the system declares that the section is occupied and the relay is dropped. This system works with two detection points only.
