C. Control Module
The control module includes hardware
loads as well as to change the required en
includes high power relays, Flip-flops and re
control module is interfaced to the GPI
controller. According to the output of the GP
of the flip flop changes which again changes
outputs. According to which the relays are
off. The flip flops are introduced as they
retain the last state of the output and only
clock is applied. This setup helps to stop th
the power at output when the controller reb
problems. Again when no power is present o
has to be powered by battery thus avoiding
to power the whole board.
