Block Signalling DAP1A Semaphore Signal Controller (signal not included)
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.
- Triggered an infra-red sensor located below the track bed
- When a train is detected passing above, the module automatically switches the signal to Clear
- When a delay (adjustable) has expired, the signal is automatically returned to Danger
- Quick and easy to set-up
- Requires a 12V DC Power Supply
