Operate Dapol Signals Automatically 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 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. There are two additional output channels which can be used to operate leds on a control panel to show remotely the status of the semaphore signal. Power Supply The module is designed for a supply voltage of 16V AC. There are separate output terminals on the module which are connected to the input terminals, and so provide the same voltage to the signals. Please double check all wiring before applying power, as incorrect wiring can damage the unit.
