   The FOUR Event Controller is the real core of our products. You will use the FOUR Event Controller to process the results of the Optical Sensors, or other triggers to display the results through the use of Lights, LEDs or other Signals.

    Our MultiSense Board is the solution to sensing a train over a long stretch of track using multiple sensors and still treating any or all of them as  ONE SENSOR. By moving the Pull-up resistors off the Four Event Controller board and stacking eight of them on one small board with the ability to combine multiple boards, we have made Optical Sensing the EASY solution to block detection.

     The Signal Light Controller is the module that makes the Approach Lighting Scheme work correctly in the Automatic Block Detection System.
