The PGCC is a fully featured circuit board providing flasher control, gate control and user=selectable bell operation. The flashers feature “fad-in and fade-out” function to simulate realistically the incandescent lamp and the “soft start” circuit found on the prototype. Includes adjustable flasher brightness, gate speed and adjustable delay between the flashers start and gates begins their decent. A built-in DIP switch enables selecting between four different prototypical bell operational sequences. The grade bell sound is provided by an integrated sound IC (GBELL1 ordered separately) pre-recorded from a prototype crossing bell.
Requires purchase of SOUND IC WITH RECORDED PROTOTYPE GRADE BELL (GBELL1)

Note: The quoted prices for all circuit boards provided by JLC Enterprises are for the fabricated boards only, that is, without any electronic parts. All circuit boards come unassembled and less components. All holes are drilled and all circuit traces are tin plated for easy soldering. Where double-sided boards are provided, all feed through holes are plated-through. The SMINI, SUSIC, RS485, DIN32, DOUT32 and PGCC boards have solder masking on both sides, silk screen legend on component side and are factory tested against shorts and open circuits.
