Our most successful product is even better now!
 

Grade Crossing Pro/2 features (NEW features added over the original Grade Crossing Pro are in RED):

bullet

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

bullet

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

bullet

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)

bullet

Adjustable gate motor speed

bullet

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

bullet

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

bullet

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!

bullet

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.

bullet

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.

bullet

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.

bullet

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

bullet

COMING SOON! Support for servo motors to operate gate arms.

bullet

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.

bullet

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

bullet

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

bullet

Solid State Design (1 year limited warranty)

bullet

$47.95 MSRP (GCP/2) [photocells]

bullet

$59.95 MSRP (GCP/2-IR) [infrared]

bullet

$39.95 MSRP (GCP/2-X) [use with external detectors]

     

Grade Crossing Pro/2 Expander


bullet

Expansion board for an additional track for use with the Grade Crossing Pro/2. Includes cable for connecting the two boards together. Use one Expander board for each additional track. For example, a 3 track grade crossing would require one Grade Crossing Pro/2 board and two Expander boards. Sensors included (four photocells or four pairs of infrared emitters and detectors). Also available without sensors for use with external detectors.

bullet

$37.95 MSRP (GCP/2-EXP) [photocells]

bullet

$49.95 MSRP (GCP/2-EXP-IR) [infrared]

bullet

$29.95 MSRP (GCP/2-EXP-X) [use with external detectors]


Bell modules and speakers

    Bell modules plug directly onto the Grade Crossing Pro/2 board. Volume adjustment on the GCP/2 board. Requires an 8 ohm speaker. Some sound clips used are with permission from Innovative Train Technology.
