GCC Grade Crossing Controller

The Grade Crossing Controller is a module which completely controls a highway grade crossing protection equipment. It provides the following features:

Detects trains approaching the grade crossing, and while blocking the road.
Starts flasher and bell audio outputs, and activates the output to lower the gates when the train enters an approach block.
Digitally synthesized audio is the MOST PROTOTYPICAL BELL SOUND available - ever.
Activates the gate raise signal after the train clears the road. Stops the bell and flasher outputs when the gates are raised.
Expandable to a total of 8 tracks crossing the road.
Manual gate raise and lower inputs to allow the crew to operate the gates when the train is stopped.
Can be used with or without operating crossing gates.
Combines grade crossing detection with your signaling system occupancy detection, if any.
Accessory in development to display the speed of a train as it passes the road.
Furnished completely assembled, with mounting hardware.
Download user's manual at no cost.
Requires a 12 VDC regulated power supply that can be shared by numerous other circuit boards.
