5234 Additional module for track occupancy detectors.

The track areas not monitored by the stay switch Art. 5208 or feedback decoder Art. 5233 should be fed via this small additional module. It prevents bridging of the track insulation between monitored and non-monitored sections by vehicles driving over them leading to an interruption of the occupancy signal. At the same time, the additional module ensures that the voltage drop in the digital voltage caused by the current sensors of Art. 5233 also occurs in the same way in the unmonitored sections in the monitored track sections. This avoids a reduction in speed when a locomotive enters a monitored area.
