Block Signalling ASP2-NS Led Signal Controller (CA) (signal not included) A compact module to automatically operate connected signals whenever a train passes over the built-in infra-red sensor. Controlling multi-aspect led signals on model railways has never been easier Detects trains passing overhead using its in-built infra-red sensor Fades signal leds in and out to simulate incandescent bulbs Very simple to connect up to signals No soldering required, all components are ready wired-up No programming required (but you can adjust all settings if you wish) For use with common-anode signals (not signals that use bulbs) Requires a 12V DC power supply
