Product Details:
BLOCKSignalling Semaphore Switcher Current Operated DAP4-BR


The Semaphore Switcher DAP4-BR is based on the BLOCKsignalling Block Occupancy Detector BOD1, but with the added ability to operate semaphore signals.

The module monitors the rails for traction current, and when it is detected, it switches the attached signal from danger to clear. For DC layouts, only trains travelling in the correct direction will trigger the signal. For DCC layouts, the signal must only be approached from the front, as trains approaching the signal from the rear will also trigger the signal.

After a pre-programmed time (default 5 seconds) the signal will switch back to danger.
