This is a
specific LED flasher function using the GPC_8A general purpose
six inputs and directly drives two LEDs which are controlled by the
inputs and flashed at two different rates.
from 12V DC
- six inputs
control LED flashing
- two LED
driver outputs (resistors are on-board)
flashes at a rate of 2 pulses per second (0.25 seconds on/off)
flashes at a rate of 1 pulse per second (0.5 seconds on/off)
Connect one or
two LEDs and a 12V power source. The normally-open connections, if
not used will have to be connected to a 0V common terminal (deactivated).
of the normally-open terminals to 0V common will start the
appropriate LED flashing.
Input 5 is a
normally open input that will start both LEDs flashing.
Input 6 is a
normally open input that will inhibit (stop) both LEDs. This can be
use as a master on/off control and takes priority over all other inputs.
Both N.O. and
N.C. inputs and Input 5 must be inactive to stop an LED flashing.
You can wire
inputs together to switch them from the same source. The LED -
connections can also be connected together for additional effects.

switched to 0V common to activate.
closed inputs must be connected to 0V common to de-activate (prevent flashing).
