Prototypical control of grade crossing signals (common anode/positive LED or bulbs) and gates

An eastbound (left to right) train will cause the signals to begin flashing when the WF sensor is activated. If a bell module is attached it will start ringing then too. If crossing gates are being used then after a short delay the gate motor outputs will turn on and the gates will lower. The signals will continue to flash even if the rear end of the train clears the WF sensor as long as the front end of the train reaches the WN sensor within 35 seconds. Assuming the train does this and then subsequently reaches the EN sensor the signals will continue flashing. Approximately 2 seconds after the rear end of the train clears the EN sensor the gate motor outputs will shut off and the gates will begin to rise. Approximately 3 seconds later the signals will stop flashing and the bell will stop ringing. If no gates are used then the signals will stop flashing and the bell will stop ringing approximately 2 seconds after the rear end of the train clears the EN sensor. If the train had not reached the WN sensor within 35 seconds of clearing the WF sensor then the Grade Crossing Pro/2 will assume the train has reversed. This “timeout” will cause the “action” to shut off as previously described above. Similar behavior exists for a westbound train with respect to sensors EF, EN and WN (shut off occurs after the last car clears the WN sensor).

"TrueLamp2" feature provides realistic fading in and out of lamps (common anode/positive LED or bulbs) while flashing.

Uses 4 sensors (included) for proper bi-directional behavior; if using photocells each one has its own sensitivity adjustment "pot". The GCP/2 provides a setup mode for making the photocell adjustment process easier. (no adjustment is necessary for the infrared version)

Adjustable gate motor speed

Handles a single track; for multiple track crossings use the GCP/2 Expander (see below).

Works with all scales; signals and gates not included (use with products made by Tomar, Details West, Oregon Rail Supply, Walthers, NJ International, etc)

Powered from 7-16V AC or DC; current draw is ~90mA (photocell version) to ~225mA (infrared version) with dual LED signals. No more special power requirements for the infrared version!

Signal outputs are turned on in sequence (Left à Right à End-of-gate arm), briefly, when power is first applied to the board. This gives you a quick test of the signals to make sure all the connections are correct and the signals work.

Individual sensor status indicators on the circuit board. These not only help you when first setting up the board but are also active when in “operating” mode.

The infrared detection method has been improved. NOTE: the IR emitter wiring is different from the previous generation product!!! Please pay close attention to this.

End-of-Gate arm LED output which is on continuously when the signals are flashing.

Support for servo motors to operate gate arms. See our Servo Motor Kit below!

On-board socket for a grade crossing bell sound module. We are offering different versions (classic, electronic, fast, Griswold) under our own brand (see below). The bell sound will fade off as the signals stop flashing.

Configuration switches for different “timing” options for lowering the gates and when the bell should be ringing.

GCP/2-X version is for use with current-sensing detectors (e.g. NCE BD20) rather than optical sensors;.
