DCC REVERSE CIRCUIT
 
Description
- fully automatic control of the loop section
- for all gauges
- for digital systems only
- with 4 sensors
- output current: 8A
- works from both directions
 
How it works
When a train enters the loop, covers the Sensor S1 (or S3 from another direction). The relay changes the polarity of the loop. 
If the train leaves the loop, covers the Sensor S2 (or S4 from another direction). The relay changes the polarity of the loop back to normal.
Both rails in both directions must be insulated! Sensors can be installed between rails.
 
Power supply
The module is powered from the track.
 
The package includes the board with 4 pcs TCRT5000 sensors.
