Block Signalling DAP1-NS Semaphore Switcher

This signal controller is designed to detect the presence of trains, and operate a semaphore signal in response.

The module detects the presence of trains by bouncing invisible Infra-Red (IR) light off the underside of the rolling stock, and detecting the light reflected back. When a train is detected, the module runs a built-in program which operates the attached semaphore signal.

  • A quick and easy way to add automation to Semaphore signals.
  • Only 4 wires to connect and you are up and running.
  • No programming required (but you can adjust all settings if you wish)
  • Operates from 9V to 12V DC or 12V to 16V AC (runs from the same power supply as the signal).
