Block Signalling ASP2A Led Signal Controller

This Signal Controller detects trains by bouncing invisible Infra-Red (IR) light off the underside of the rolling stock, and detecting the light reflected back. Once triggered by the train, the module runs built-programs to simulate the operation of 2-, 3- or 4-aspect signals.

  • Uses an infra-red sensor mounted below the track to detect trains passing above
  • When a train is detected, the module triggers the signal to switch to red
  • Signal automatically switches back to green (through yellow and double-yellow if appropriate)
  • Flexible programming options to suit different signals and to allow adjustment of timings to suit
  • Designed for signals which need +12V to be switched to them to light their leds (common cathode)
  • Realistic fading between aspects.
  • Yellow and Double-Yellow stages will change to red if another train passes.
  • For Common-Anode led signals only
