8.9 INPUT AND OUTPUT CIRCUITS
The above devices are directly controlled and monitored by the CPU. The
solenoids and indicator panel are energized with +24 volts. The sensors and
switches are energized with +12 volts or +5 volts.
To energize a solenoid or indicator, the CPU drops the connected trigger line
from +24 volts to LOW. The CPU monitors the input lines of the sensors and
switch to determine when they are activated.
