Sensors mount between the rails and activate circuitry when shaded from a passing train. The FOM-1 is similar to the block module with the exception that it uses an external optical sensor to detect train movement. When the 2nd train arrives, the Sensor is already active, so the value is unchanged (but the value can only be a single object anyway) When the 1st train leaves, the Sensor stays active, so the value remains that of the 1st train; The assumption is that a train will only go through a set turnout. • Position sensor - detects the presence of the train as the train passes directly over the sensor. When there's no light detected, the IR detector returns a high signal, around 5 volts. Turnout Control, Block Detection, Lighting & Sound Effects. Trains passing overhead block the light, triggering the sensor. Built-in sounder with 18 real sound samples. Paramount to most C/MRI applications is the need for the computer to be able to determine which sections of track are occupied.
